▼ Anti-icing agents are applied to road surfaces to prevent ice formation and to melt any hail or snow as it falls. The specific agent is selected to provide optimum anti-icing properties for the particular local climate in different municipalities taking into account cost, availability and properties. These anti-icing agents are generally applied in liquid form, and due to their low freezing temperatures, are able to remain liquid at the low ambient temperatures. Unfortunately, the negative aspect of the use of liquid agents is that they are able to penetrate concrete structures to a greater extent than can the solid de-icers, such as rock salt. Once the chloride solutions penetrate the concrete, they can have serious deleterious effects on both the reinforcing steel as well as the concrete [1]. It has been shown in previous studies that the cations of the solutions will tend to react with the cementitious materials to form precipitates of expansive nature. More specifically, the reaction of CaCl2 with Ca(OH)2 results in the formation of expansive calcium hydroxy-chloride [2]. The reaction of MgCl2 with Ca(OH)2 forms Mg(OH)2 in the capillary pores with CaCl2 as a by-product after which the MgCl2 can react with the calcium-silicate-hydrate to form magnesium-silicate-hydrate – a gel-like material with no inherent binding properties or strength. The calcium hydroxy-chloride and Mg(OH)2 precipitates can have a positive effect at early onset, but will eventually cause deterioration of concrete due to the internal forces applied by the precipitates as their volume increases. This can affect the strength and create notable interior strain in the concrete. There are a number of mechanical properties that can be analyzed using short-term testing that will help to determine any changes occurring due to salt solution exposure. To gain a general understanding of the effects of the salt solution exposure in this project, compressive strength, tensile strength, elastic modulus, and strain were measured using a number of exposure conditions. While the results of testing confirm that there are initial benefits beyond minimizing ice formation and bonding, there ultimately exist a number of concerns with respect to the reactions that occur between the salts and hardened cement paste. Although the formation of calcium hydroxy-chloride is known to be expansive [3], evidence of this compound was only seen indirectly through elevated strain and micro-cracking. There was no deterioration of compressive strength, tensile strength, or elastic modulus over the short-term testing. Similarly, and again due to the short testing period, the formation of magnesium-silicate-hydrate (M-S-H) is unlikely to have occurred, though its formation during long-term exposure can result in complete loss of binding strength [2]. However, the precipitation of Mg(OH)2 is believed to be responsible for the lower chloride diffusion rate as well as the increase in strength of the concrete exposed to MgCl2. The only agent which did not yield…

▼ Operations in glaciated conditions are a threat to commercial aviation. The ingestion of ice crystals can affect different aircraft probes but can also affect jet engines. As fully frozen ice crystals enter an engine, partial melting occurs on the low-pressure compressor region of the engine, and ice accretion could occur on warm surfaces due to the presence of water coupled with the cooling capacity of the unfrozen portion found on the particles. Understanding the fundamental fracture dynamics that occur when partially melted ice crystals impact a surface is needed for model development and verification. To experimentally measure such fracture/splashing dynamics, a test rig was designed and fabricated to observe the impacts of partially melted ice particles. Ice particles ranging from 403 μm to 1028 μm were suspended on an ultrasonic levitator and were allowed to melt under natural convection. A fluorescence-based technique was used to quantify the water content of the melting ice particle in real time. A pneumatic launcher was automatically triggered at a requested water content to ice ratio, and a stainless steel impactor was launched at speeds ranging from 2.8ms−1 to 65.5ms−1. The impacts were recorded with a high-speed camera at 75000 frames per second. The qualitative behavior of these impacts was observed, and an empirical model to determine the threshold velocity for an ice particle to fracture for four different water content to ice ratios was proposed. From this empirical model, when the partial melting was 79%, the impact velocity required to fracture a particle increased by 81% from its value for the fully frozen cases. Moreover, during the data acquisition process, a new technique to measure the water content of a melting ice particle based on the diameter of the ice core observed post impact for the non-fractured events was proposed. This direct measurement technique was compared to the fluorescence-based water content quantification techniques to further understand partial melting quantification uncertainties.

▼ High altitude ice crystal clouds created by highly convective storm cells are dangerous to jet transport aircraft because the crystals are ingested into the compressor section, partially melt, accrete, and cause roll back or flame out. Current facilities to test engine particle icing are not ideal for fundamental mixed-phase ice accretion experiments or do not generate frozen droplet clouds under representative conditions. The goal of this research was to develop a novel facility capable of testing fundamental partially melted ice particle icing physics and to collect ice accretion data related to mixed-phase ice accretion. The Penn State Icing Tunnel (PSIT) has been designed and fabricated to conduct partially melted ice particle cloud accretion. The PSIT generated a cloud with air assisted atomizing nozzles. The water droplets cool from the 60psi pressure drop as the water exited the nozzle and fully glaciate while flowing in the -11.0°C tunnel air flow. The glaciated cloud flowed through a duct in the center of the tunnel where hot air was introduced. The temperature of the duct was regulated from 3.3°C to 24°C which melted particle the frozen particle from 0% to 90%. The partially melted particle cloud impinged on a temperature controlled flat plate. Ice accretion data was taken for a range of duct temperature from 3.3°C to 24°C and plate temperature from -4.5°C to 7.0°C. The particle median volumetric diameter was 23µm, the total water content was 4.5 g/m3, the specific humidity was 1.12g/kg, and the wet bulb temperature ranged from 1.0°C to 7.0°C depending on the duct temperature. The boundaries between ice particle bounce off, ice accretion, and water run off were determined. When the particle were totally frozen and the plate surface was below freezing, the ice particle bounced off as expected. Ice accretion was seen for all percent melts tested, but the plate temperature boundary between water runoff and ice accretion increased from 0°C at 8% melt to 3°C at 90%. There were two types of ice accretion with a transition zone in between. The first type of ice was opaque in color and had a rough surface. This ice occurred roughly from 6.0°C to 12.0°C duct temperatures (8% to 50% melt). The qualitative characteristics of the ice were produced from the low water content in the cloud. The water that was available froze instantly and trapped ice particle. Duct temperatures greater than 17.5°C (80% melt) produced ice that was clear and smooth. The water in the surface did not freeze instantly due to the high water content creating a water film that froze. A mixed-phase cloud dynamics model from NASA Glenn was used to estimate the percent melt of the cloud exiting the duct. There was no way to validate the model by directly measuring the percent melt of the cloud, so single particle melt experiments were conducted and compared to the model. A 0.05g/L solution of rhodamine b was sprayed into a levitator and droplets formed at the nodes of the wave. A 532nm green laser was used to illuminate the dye, and the water… Advisors/Committee Members: Jose Palacios, Dissertation Advisor/Co-Advisor, Jose Palacios, Committee Chair/Co-Chair, Robert Francis Kunz, Committee Member, Michael H Krane, Committee Member, Stephen P Lynch, Outside Member.

▼ The goal of this research was to design a helicopter rotor blade lead edge that had high sand erosion resistance and was conducive to ultrasonic ice protection systems (IPSs). The first section of research tried to tailor the leading edge to promote ice interfacial transverse shear stress created by the ultrasonic vibration of piezoelectric actuators. Previous work done to tailor leading edges removed material from the inside of the cap. However, there were concerns about structural integrity and erosion wear when material was removed. A new system of adding material to the inside of the leading edge instead of removing material to create stress concentrations was researched for this thesis. Finite element analysis was used to determine the optimal locations for the discontinuities for the ultrasonic IPS. The discontinuities located in the optimal location are called Tailored Stress Concentrators (TSCs). Using the finite element results, it was determined that the best location for the TSCs were in regions of normally low stress in the baseline model before the addition of the TSCs. The addition of the TSCs creates stress concentrations as well as increased the original local maximum stresses. Initial models showed increases in average interfacial shear stress of 20%. Since the first FEM was not practical to construct as a bench top experiment, a second model was developed. Next, a bench top experiment and matching finite element model were built to validate the finite element analysis. The finite element model predicted a decrease of 9% in interfacial shear stress when TSCs were added to the bench top model. The bench top experiments confirmed the ineffectiveness of TSCs. There was no reduction in power required to de-ice when the TSCs were added to the bench top model. The next part of the research focused on the material used for the leading edge erosion cap. Coating systems based on titanium nitride (TiN) applied via cathodic arc physical vapor deposition (CA-PVD) were developed for rotorcraft erosion caps to protect against sand and rain erosion. Erosion resistant materials must also be compatible with ice protection systems. The ice adhesion strength of titanium nitride and titanium aluminum nitride (TiAlN) were evaluated experimentally and compared to the ice adhesion strength of uncoated metallic materials currently used on rotor blade leading edge caps: stainless steel 430, Inconel 625, and titanium grade 2. Experimental studies presented in this paper investigated which environmental and material parameters are most influential on impact ice adhesion strength. The effects of median volumetric diameter, liquid water content, ambient temperature, surface roughness, and material grain direction were tested on stainless steel 430. Tests revealed that surface roughness and temperature have the greatest effect on ice adhesion strength. There was an increase in adhesion strength of 670% from -8°C to -16°C and 250% increase from 24 Ra µin to 105 Ra µin. An increase in water droplet size from 20 µm to 40 µm… Advisors/Committee Members: Jose Palacios, Thesis Advisor/Co-Advisor, Douglas Edward Wolfe, Thesis Advisor/Co-Advisor.

▼ In-flight ice accretion on fixed-wing aircraft and rotorcraft can be catastrophic if not mitigated. Most modern ice protection systems are active systems, which require electrical or mechanical power to remove accreted ice. Despite their proven capability to protect aircraft from ice accretion, these methods can reduce the aerodynamic efficiency of the vehicle and increase its weight, cost, and complexity. Scientists and engineers now seek passive, erosion-resistant materials and coatings with low ice adhesion strength. Ideally, such materials, when applied to vulnerable components of an aircraft, would cause any ice to shed off the surface under normal aerodynamic loading. To aid in the development of low-ice-adhesion-strength materials, the growth and structural behavior of impact ice in a wide range of atmospheric conditions must be characterized. Facilities such as the NASA Icing Research Tunnel (IRT), the Anti-Icing Materials International Laboratory (AMIL), and the Penn State Adverse Environment Research Testing Systems (AERTS) laboratory, to name a few, have spent decades investigating the relationship between ice adhesion strength, temperature, surface roughness, airspeed, and other parameters. The structural behavior of ice has been examined under pure shear, tension, and compression, and mixed-mode loading. However, one important loading consideration that has not been widely investigated on atmospheric ice is strain rate. Very few published ice adhesion studies report the strain rate applied to the ice samples. Several previous studies of laboratory-prepared ice in compression revealed that ice undergoes a ductile-to-brittle transition under high strain rate conditions, and that the adhesion strength is a power function of the strain rate. Other studies, in which lab-prepared ice was loaded in pure shear, reported similar trends. It is unclear whether the same behavior can be expected of dynamically-accreted atmospheric impact ice. Knowledge of the relationship between impact ice adhesion strength and strain rate is important because it can be used to design future ice protection systems, and it may dictate the appropriate course of action for a pilot flying through icing conditions—for instance, whether a helicopter pilot should increase the rotor speed rapidly or slowly to induce shedding of the ice. NASA Glenn Research Center funded the design and construction of a new centrifuge-style ice adhesion test rig (“AJ2”) by the Penn State AERTS lab. The ice is accreted dynamically by spinning flat metal test coupons at high speed inside a simulated icing cloud environment, so the water droplet sizes and impact speed are representative of in-flight icing, without the need for a wind tunnel. The rig motor allows for user-defined acceleration rates, so the strain rate on the ice can be controlled. The adhesion strength of the ice is calculated from the voltage output of strain gauges mounted on the cantilever beams holding the test coupons. Unlike other small-scale adhesion test methods, AJ2 allows… Advisors/Committee Members: Jose Palacios, Thesis Advisor/Co-Advisor.

▼ The Northern Plains region of the United States is home to a significant amount of potential wind energy. However, in winter months capturing this potential power is severely impacted by the meteorological conditions, in the form of icing. Predicting the expected loss in power production due to icing is a valuable parameter that can be used in wind turbine operations, determination of wind turbine site locations and long-term energy estimates which are used for financing purposes. Currently, losses due to icing must be estimated when developing predictions for turbine feasibility and financing studies, while icing maps, a tool commonly used in Europe, are lacking in the United States. This study uses the Modern-Era Retrospective Analysis for Research and Applications (MERRA) dataset in conjunction with turbine production data and in-situ wind measurements to investigate six methods of predicting seasonal losses (October-March) due to icing at two sites located in Petersburg, ND and Valley City, ND. The prediction of icing losses is based on temperature and relative humidity thresholds and is accomplished using six methods. Three methods use a Measure-Correlate-Predict (MCP) and flow model (WAsP) analysis for the determination of wind speeds and MERRA for temperature and relative humidity, while three methods use MERRA for all three variables. For each season from 2002 to 2010, the predicted losses due to icing are determined for a range of relative humidity thresholds and compared with observed icing losses. An optimal relative humidity is then determined and tested on all seasons from 2002 to 2013. The prediction methods are then compared to a common practice used in the wind energy industry of assuming a constant percentage loss for icing over the same time period. The three methods using MERRA data alone show severe deficiencies in the accurate determination of wind speeds which leads to a large underprediction in accurate power output. Of the three MCP/WAsP methods, the method using boundary-layer similarity theory to determine temperature and relative humidity shows the most accuracy in predicting icing losses closest to observed losses at the Petersburg location with an average absolute difference of 2.13 % ± 1.29 %. This is a significant improvement over using a constant value which produces an average absolute difference of 5.87 % ± 4.64 %. Analysis at the Valley City location shows similar results when the datasets are retrained to that location. Advisors/Committee Members: Gretchen Mullendore.

▼ Icing is a lethal and costly aviation hazard affecting aircraft of all sizes ranging from small UAVs to large commercial craft such as the Boeing 787, resulting in hundreds of deaths over the last century and resulting in billions of dollars of economic impact. Three predominant types of icing, namely, airframe icing, engine icing, and rotorcraft icing, dominate aircraft icing research. Each type poses unique challenges. In the case of rotor icing, attention needs to give to the rotating environment with large oscillatory loads and icing conditions. In the case of airframe icing, special attention needs to be paid to a variety of loading cases from the available options for de-icing and anti-icing equipment. In the case of engine icing, the formation mechanism is poorly understood and the structure of the ice needs to be studied in greater detail. Airframe icing requires However, all three share the same fundamental problem that ice sticks to surfaces. How strongly ice adheres to a surface dictates how hard it is to remove. The adhesion strength then regulates the primary threat from icing - the maximum aerodynamic penalty that accretion will have. It also dictates the threat of impingement from shed ice elsewhere on the aircraft, such that a piece of ice from the main rotor could strike the tail rotor on a helicopter, destroying it. There exist many methods to evaluate the adhesion of ice to a given substrate, the most common being pusher tests and centrifuge tests. These and other methods are problematic in evaluating the adhesive properties of ice to a substrate in aircraft icing conditions; no data in the literature exists that accounts for stress concentrations at the interface and the strain rate at the interface, and no data was found in the literature on the grain structure of impact ice at speeds relevant to aircraft icing. A new method to measure the adhesion of impact ice has been developed based on a lap joint shear test. Lap joint tests are common in adhesion measurements since they produce nearly uniform stress at the interface of interest. In support of this end, a new shear rig and a new wind tunnel model for the Icing Research Tunnel were designed and fabricated. Six nights of testing in the Icing Research Tunnel were conducted to obtain samples, which were later tested in a laboratory environment. The tests were displacement controlled and samples were tested at four crosshead speed rates. The grain structure of the ice was documented using a cross-polarized optical microscope for the first two nights of testing, showing significant differences in the grain structure dependent on velocity and whether the cloud was in the SLD range or not. Correlations with temperature and test section velocity are demonstrated. It was also demonstrated that residual stresses, which are unaccounted for in the literature, play a significant role in the adhesion of impact ice. Options to improve the test methodology further are discussed. Finally, a shedding model predicting the trajectory of ice at a shed event has… Advisors/Committee Members: Lian, Yongsheng, Cobourn, Geoffrey, Cobourn, Geoffrey, Williams, Stuart, Willing, Gerold.

▼ Atmospheric icing, the process by which supercooled water droplets freeze upon contact with a surface, has proven to be devasting when not controlled or prevented. Currently, the solution for addressing this problem is the use of deicing fluids, which are toxic and inefficient, leading to the development of intrinsically anti-icing materials to focus on prevention rather than response after manifestation. Amphiphilic polymer coatings have been of particular interest as they are capable of presenting complex nano- and microscopic heterogeneities for inhibition of ice formation, which is not a typical approach toward anti-icing technologies. We have previously synthesized crosslinked networks comprised of hyperbranched fluoropolymers (HBFP) and poly(ethylene glycol) (PEG), which demonstrated superb anti-biofouling capabilities credited to their amphiphilic morphology, nanoscopic surface topography and dynamic surface reorganization. Through the tuning of the amphiphilicity and thermo-responsive molecular ordering of this crosslinked hyperbranched network, we expand the application of these materials by exploiting their characteristics for development of robust, dynamic, anti-icing coatings for aerospace applications. An array of films was synthesized by varying the PEG crosslinker to study the effect of hydrophilic:hydrophobic component ratios on the thermal, mechanical and surface properties. Differential scanning calorimetry (DSC) data show significant reductions in the water melting transition temperatures (-5 ⁰C and -27 ⁰C for free and bound water, respectively). The novel application of this system displays the expansion and diversity of a well-established coating that demonstrates unique water confinement and sequestration behaviors with the ability to reorganize at the surface. Due to its great potential as an anti-icing coating, additional investigations and chemical manipulation of the binary system led to the integration of a thermally-dynamic molecule, a liquid crystalline (LC) moiety. A library of LC systems was developed in order to probe the effects that size, mesophase and topology would have on the water depression efficiency of these materials. An LC monomer was incorporated into the polymer during polymerization in order to enhance the dynamic reorganization of the system during changes in temperature and wetting. The results suggest that the unique LC-HBFP system is a viable option as a dynamic coating for extreme environments.

▼ Performance degradation of rotor blade ice shapes was computationally investigated for several icing conditions. The ice shapes were accreted in the Adverse Environment Rotor Test Stand (AERTS) at Pennsylvania State University, and digitized to provide 2D slices of the iced blade. Hybrid, viscous sub-layer resolved grids were created in order to capture these ice features. Several sub-layer turbulence models were applied. For 2D cases, drag predictions obtained with the NPHASE-PSU Computational Fluid Dynamics (CFD) code compare favorably with drag data from several data sources including the AERTS experimental facility. Iced airfoil drag is primarily due to form drag associated with the bluff effective leading edge ice shapes, effects which are well captured. However, predicted lift values deviate signi�cantly from the experimental data at high angles-of-attack, consistently underpredicting stall onset and high-alpha-lift. Parametric exploration of the causes of these discrepancies was pursued. Specifcally, experiments performed in NASA Glenn's Icing Research Tunnel on two additional airfoil geometries with accreted glaze ice shapes were modeled. These studies show that 2D RANS turbulence modeling consistently leads to this same inaccurate lift prediction behavior, and that this observation is consistent with other studies that have appeared in the literature. These shortcomings are hypothesized to arise due to the well known challenges that 2D RANS turbulence models have in adverse pressure gradient flows, stagnating flows, and flows with strong curvature and also due to the inherent three-dimensionality of the ice shape and the unsteady recirculation regions aft of the sharp ice shape separation points. In order to explore the role of 3D and unsteady flow effects, a CT scan of one of the full 3D AERTS ice molds was used to create a large 3D grid. NPHASE-PSU was run using an Implicit Large Eddy Simulation (ILES) turbulence model. These results indicate that incorporation of three-dimensionality and large scale unsteadiness (upper inertial range) are important in capturing the aerodynamics in these systems.

▼ Unmanned aerial system (UAS) is a hot topic in both industry and academia fields. As a popular planform, the rotary-wing system gains more attentions. The small UAS propeller is the most important component in this system, which transfers electric energy into kinetic energy to accomplish fly missions. In the present work, several experimental studies have been performed to investigate the aerodynamic and aeroacoustic characteristics of small UAS propellers. First of all, by conducting force and flow filed measurements, the unsteady dynamic thrust and the wake structure of the propeller has been studied to explore the fundamental physics to help researchers and engineers to obtain a better understanding. Secondly, two kinds of bio-inspired the propellers have been designed and manufactured. Through a set of force, sound, and flow filed measurements, the aerodynamic and aeroacoustic performance of these propellers has been compared to the baseline propeller to evaluate the effects of aerodynamic efficiency and noise attenuation. It was found that the serrated trailing edge propeller could reduce the turbulent trailing edge noise up to 2 dB, and the maple seed inspired propeller could reduce the noise up to 4 dB with no effect on the aerodynamic performance. In addition, since the rotary-wing system consists more than one propeller, the rotor to rotor interaction on the aerodynamic and aeroacoustic performance also has been studied. By enlarging the separation distance between two propellers, the thrust fluctuation and noise generation could be restricted. Not only the design of the device itself has effect on the flying performance, the extreme weather also would affect it. Therefore, an icing research study on the small UAS propeller has been conducted to illustrate how does the ice formed on the propeller and how does the icing influence the aerodynamics performance and power consumption. During these experimental studies, the force measurements were achieved by a high sensitive force and moment transducer (JR3 load cell), which had a precision of ÃÂ±0.1N (ÃÂ± 0.25% of the full range). The sound measurements were conducted inside of the anechoic chamber located in the aerospace engineering department at Iowa State University. This chamber has a physical dimensions of 12ÃÂ12ÃÂ9 feet with a cut-off frequency of 100 Hz. The detailed flow structure downstream of the propeller was measured by a high-resolution digital PIV system. The PIV system was used to elucidate the streamwise flow structure downstream of the propeller. Both “free-run” and “phase-locked” PIV measurements were conducted to achieve the ensemble-average flow structure and detailed flow structure at certain phase angles.

▼ Aircraft icing is widely recognized as a significant hazard to aircraft operations in cold weathers. Bio-inspired water- and ice-phobic coatings are currently being investigated for use as viable strategies for aircraft in-flight icing mitigation. The objective of this study is to evaluate the anti-/de-icing performance of a number of bioinspired hydro-/ice-phobic coatings and explore their potentials for aircraft in-flight icing mitigation. In the present study, the bioinspired hydro-/ice-phobic coatings examined include the lotus-leaf-inspired super-hydrophobic surface (SHS), the pitcher-plant-inspired slippery liquid-infused porous surface (SLIPS) and the goose-feather-inspired textured surface. Firstly, a comprehensive experimental study was conducted to investigate the dynamics of impacting water droplets onto the test plates with SHS, SLIPS and goose feather surface, in comparison with that of over a conventional hydrophilic aluminum surface. A novel wind tunnel was built to accelerate the droplets to the Weber number up to 3,000, in the range relevant to aircraft in-flight icing phenomena. A high-speed, high-resolution system was used to reveal the droplet impact dynamics at the high Weber number regimes. Secondly, a new anti-/de-icing strategy with icephobic soft materials (e.g., made from PDMS gels) was also explored for aircraft anti-icing applications. The effects of surface stiffness on the dynamics of droplet impingement at high Weber numbers were investigated in great details. The soft surface was also applied to an airfoil/wing model to demonstrate its effectiveness for in-flight icing mitigation in the unique icing research tunnel of Iowa State University (i.e., ISU-IRT). Thirdly, the durability of various surface coatings due to spray erosion pertinent to aircraft icing mitigation scenario was also experimentally investigated and compared for the bio-inspired hydro-/ice-phobic surface coatings. Surface morphology, wettability, and ice adhesion strength were compared quantitatively after different spray erosion testing durations. A theoretic wettability-based lifetime model was developed following the Cumulative-Fatigue-Damage theory to predict the spray erosion characteristics of the bio-inspired hydro-/ice-phobic surface coatings. Fourthly, Particle Image Velocimetry (PIV) technique was used to measure the flow fields around wind-driven droplets on surfaces with various wettabilities. A theoretical model based on force balance analysis was developed to predict the critical wind speed which dislodges the droplet from the solid surface. Finally, wind-driven droplet motion on SLIPS was provided with more details by measuring the flow field inside and outside of the droplet simultaneously using the PIV technique. It showed that wind-driven droplet internal circulation is related to the droplet viscosity and it will influence the prediction of the droplet moving speed. The findings derived from this study could be very helpful to explore/optimize design paradigms for the development of innovative,…

▼ Oyster harvesting is a major industry along the Eastern and Gulf coasts of the United States. Eastern oysters (Crassostrea virginica) spawn when the waters start to warm between May and October in the Gulf of Mexico. The warmer temperature creates a problem with an increase of bacteria. The two major bacteria affecting the oyster industry are Vibrio vulnificus and Vibrio parahaemolyticus. These bacteria are the leading causes of seafood-borne illnesses in the United States. This increase of V. vulnificus and V. parahaemolyticus has led to stricter time/temperature requirements for harvesting oysters. The regulations are not plausible for smaller vessels too small to hold a refrigeration unit. Chilling the oysters to lower Vibrio levels using an on-board icing unit was proposed for further investigation. The oysters were tested for V. vulnificus and V. parahaemolyticus at each stage along with tested for gaping after 7 and 14 days in refrigerated storage. This experiment was conducted in May, July, and September 2015. The results will help advance the use of triploid oysters as viable options for the oyster industry during the spawning of diploid oysters. The total Vibrio parahaemolyticus and Vibrio vulnificus results were log10 transformed to compare the treated and controlled data for all three months. The data was run through a mixed procedure in SAS 9.4. The V. parahaemolyticus showed a significant difference in the sampling months (p<.001) but not a difference in the treatments (p=0.4715). The differences in the Vibrio vulnificus sampling months were significant (p<0.001) but not the treatments (p=0.2617). Pathogenic V. parahaemolyticus was not flourishing in this area. A difference could not be found in the months or treatment because of the low amounts of bacteria. The gaping data was significantly different between the iced and controlled oyster sacks (p<.001) along with the sampling months (p=.0014). Further work is needed to improve this design and process.
