▼ In this study, established a two dimensional CFD model with orthogonal mesh to simulate the combustion phenomenon of methane-air mixture gas in the radiation combustor. The combustion chamber of this model which consists of a cellular array was simplified to modeling flame propagation inside a channel, and therefore parameters effects of flame ignited location and efficiency of this combustor has been discussed. Using ANSYS FLUENT and user-defined function (UDF) to simulate flame propagating and heat radiation, and using DO model of ANSYS FLUENT to simulate surfaces emissivity. In this study, considering methane and air stoichiometric combustion modeled by a simple one-step irreversible reaction The results reveal that increase of thermal conductivity results in the increase of adiabatic flame propagating speed and temperature, and thus flame propagats to upstream side. However, when thermal conductivity greater than 20 W/m-K, it was limited for the effects of thermal conductivity to increasing adiabatic flame temperature. If the inlet fuel velocity increase, it needs longer distance to achieve 100% fuel consumption. Flame propagating to the downstream side heats the methane-air mixture gas closed to the downstream side, increases downstream radiation heat flux , reduces radiation heat loss flux to the environment of upstream side and results in worse combustion efficiency. With certain equivalence ratio, at the limit fuel inlet velocity, it causes the maximum adiabatic temperature, but with large solid thermal conductivity it can employ wide range of fuel inlet velocity. With case of large equivalence ratio, adiabatic flame speed and temperature, it needs a shorter distance to achieve 100% fuel consumption, also leads to flame propagate to the upstream side and increases the radiation heat loss. Downstream radiation heat efficiency would increase with increasing perforated-plate internal emissivity. Overall, using a combustor which consists of lower equivalence ratio, lower fuel inlet velocity, lower perforated-plate conductivity, and higher perforated-plate internal emissivity,will gain better radiation heat efficiency.

▼ Flame behaviors and stability limits of the two-dimensional steady premixed flame in one-step tubes are investigated numerically in this study. In this study, the complete Navier-Stokes equations are used in the mathematical formulation and the flame chemistry is modeled by a simplified four-step reduced reaction mechanism of methane-air mixture. The steady premixed flames in the one-step tubes are studied. Parametric investigations are carried out to understand the effect of average inflow velocity, mixture equivalence ratio, expansion ratio of the tube and wall-temperature on reattachment length, flame position, flame shape, distribution of gas mole fraction and flame stability limits. It was observed that the recirculation zone, created due to sudden flow expansion, at the backward step significantly modifies the flow velocity profile and directly changes the combustion reaction mechanism, however the flame position will indirectly affect the distribution of the flow field. The inflow velocity is varied so as to cover all possible flame positions inside the domain. Three expansion ratio, 1.67, 2.5, 5, have been considered. Three flame behaviors have been observed when ER is 5, which are mushroom-shaped flame, tulip-shaped flame and asymmetrical tulip-shaped flame. Four flame behaviors have been observed when ER is 2.5, which are mushroom-shaped flame, tulip-shaped flame, asymmetrical tulip-shaped flame and slant-shaped flame. Five flame behaviors have been observed when ER is 1.67, which are weak flame, mushroom-shaped flame, tulip-shaped flame, asymmetrical tulip-shaped flame and slant-shaped flame. Results show that the lower the wall-temperature and the mixture equivalence ratio, the smaller the flame stability limits range are, the fewer the types of flame shape are and the larger the increments of flame displacement become, and vice versa.

▼ Fuel lean combustion is used in non-premixed flame burner designing, power and fuel usage are the most considered factors. In order to decrease fuel usage, preheat input air is a normal way to reach the target power. This method can save the chemical energy in fuel from heating cold fresh air, enhance combustion reaction, but it will form higher peak flame temperature, and create a local high temperature zone in combustion chamber. Due to the formation of NOx strongly relating to temperature, higher temperature causes more NOx formation and emission under same oxygen concentration condition. To reduce NOx formation and emission, EGR method collects hot exhaust gas and mixes it with fresh air. The method dilutes oxygen concentration and reduce the combustion reaction rate. It also heat up colder fresh air, which is also another way to save fuel usage. Firstly, a multi-step dimensionless combustion model is used to calculate an Air/Fuel = 11 methane combustion, adiabatic flame temperature and species. Target adiabatic flame temperature is set up, and then we calculate the fuel usage for using EGR method and preheat fresh air combustion. A two dimension combustion model is built with target power 89000 kcal/hr. The two dimensional combustion model shows flame features and NOx distribution. Compare and analyze the results between di-mensionless and 2-D model. EGR method and preheating fresh air does not simultaneously apply in industrial burner. This study simulated non premixed combustion with power 89000 kcal/hr and air fuel ratio=11, and using EGR method and preheating fresh air. Results show that max reduction of NOx emission 65%, max fuel usage reduction 68%. Research provides qualitative analysis for non-premixed burner under different EGR ratios and different temperatures preheated fresh air, which can predict NOx emission and flame characteristic for burner designing.

▼ Carbon accumulation occurs significantly on the walls of inside a coke oven and it may cause serious blocking problems during the coke-making operation. Therefore, the coke oven is scheduled regularly to burn the accumulated carbon under maintenance. Due to the slow combustion rate of deposited carbon, the maintenance time is often long and reduces the yield rate. The study focused on a 3D unsteady coke oven burning model to simulate the real coke oven including heat blocking materials It simulated different convection conditions, which were natural convection, force convection by air blower and force convection by a nozzle pipe, to assist field personnel to select the best operating mode. The burning rate of solid carbon is dominated by the oxygen diffusion, so a forced inflow is proposed to increase the carbon-burning rate. However, if the air inflow rate is too high, it will lower the oven wall temperature and consequently the carbon-burning rate may be slowed down, even terminated. The results showed that more fresh air flow could increase coke burning rate. When flow rate was too high and cool down the oven wall temperature, it may be below the brick safety temperature and the wall brick was damaged. Comparing the simulation results of force convection by air blower and a nozzle pipe, it showed that when the mass flow rate of force convection by a nozzle pipe was 33% smaller than that by air blower, the coke burning rate was 13% higher than force convection by air blower and the burning location was closer to the thicker coke zone. Thus, the method using the forced convection by a nozzle is more time-efficient to coke burning operation. In these three conditions natural convection resulted in an unstable flow field and the coke burning position will change a lot, while the flow field of force convection by air blower could quickly reach a relatively stable state. As a result, a steady state simulation of forced convection by air blower can be used to evaluate the coke burning rate and shorten the simulation time.

▼ To develop the process of bottom blowing steelmaking, a good tuyere design is the core technology. Such a good design can cool down the molten iron around the tip of a tuyere to be solidified, and this solidified region named âmushroomâ can protect the tuyere and the furnace refractory from erosion. In this study, a 2D axisymmetric computational fluid dynamics model was built, according to the flow fields observed from the water model experiments using a double tuyere composed of an inner tube and an outer tube. This model was to investigate the influence of the mushroom thickness and hydrocarbon flow rate on the hydrocarbon pyrolysis and understand the role of co-injected hydrocarbon gas in the bottom-blown oxygen steelmaking. In a practical process, oxygen was injected from the inner tube, and hydrocarbon, which is propane in this study, was between the outer tube and inner tube. Propane is used as the protecting gas around oxygen from an early combustion. It was assumed that a main stream of the blowing gases is formed through the vent to the pressure outlet boundary. The propane pyrolysis was computed using a multistep combustion model. The simulation results showed that the adopted propane flow rate in this study is so large that the propane decomposed at the brink of main stream. Moreover, propane is mixed well with oxygen after blown out the tuyere. Thus the location of combustion occurred after that of pyrolysis. Despite the fraction of pyrolized propane is low, the pyrolysis still can increase the heat absorption from the molten iron by around 30%. When the mushroom is formed, it blocks the heat convection from molten iron to gases and causes the pyrolysis rate lower. Thus the thicker the mushroom is, the lower the pyrolysis rate is. When the mass flow rate of propane increased, the mixing distance of gases at the wall was longer and resulted in more heat absorption. However it would result in a lower temperature on the wall and the pyrolysis rate was lower. As a result, the key factors of hydrocarbon pyrolysis in bottom blowing process are the flow rate of hydrocarbon, wall heat flux as well as the mixing condition of hydrocarbon and oxygen. The cooling effect from hydrocarbon pyrolysis can get better by separating the hydrocarbon and oxygen. This would induce longer mixing length to allow a larger propane pyrolysis rate and adsorb more heat from the molten iron to improve the mushroom growth.

▼ Applying an intumescent fire-retardant coating to a substrate is an effective and passive method for fire protection. To better understand the coating performance, two different laboratory-scale tests were established in this study to investigate the effects of convective and radiative fluxes on the coating. In addition, the corresponding numerical models were also developed to obtain the thermal flow fields, which are difficult to measure, in the tests. Experiments combined with numerical models can further understand the coating performance in actual fire conditions. Two different heat sources (radiation and convection) were individually applied to a 100 mm x 100 mm substrate covered by intumescent coating. The radiative and conductive heat fluxes were respectively provided by a hot plate and a burner for 30 and 20 minutes. The thermal response of coating were recorded by using a camera. In addition, the temperatures of the coating and the substrate, and the heat flux at the back side of substrate were also measured. Therefore, the coating response for different types of heat source can be observed and analyzed from the measurements. Very different coating performances were found between the radiative heat source and convective heat source. Because it is difficult to measure the gas flow fields from the experiments, the corresponding three-dimensional models were used to analyze the gas flow fields and the thermal effects on the coating surface. It is found that, in the test of radiative heat flux, the convective heat loss on the coating surface is about 4% and can be ignored. Moreover, in the test of convective heat flux, the burner cannot provide a uniform convective heat flux, therefore, the model results can help understand the distribution of convective heat flux applied on the coating surface. Therefore, the numerical models take an important role on analyzing the defects in bench-scale tests in this study. Using bench-scale tests, the coating performance can be easily obtained and analyzed, so the implement of coating on a protected sample can be better determined before a large-scale test, which can help reduce the costs of time and money. In addition, the bench-scale tests can give a better understanding of coating in the heating process, so they can be used to examine the performance of new coating formula.

▼ The bottom-blowing process of the converter accelerates the erosion of refractory material near the tuyere and the tuyere tip. If the damage mechanism is understood and controlled, the life of the converterâs refractory material can be extended. This study simulates the water modelâs bottom-blowing erosion experiment by using two phase flow VOF model, testing the degree of damage on the wall near the tuyere which was caused by gas back-attack in different bottom-blowing of flow rate. This study finds that the simulation result has great correspondence with the data of the experiment. The flow rate of bottom-blowing grow and the range of erosion expanded at the same time when the flow rate is low. However, when the flow rate gets to the critical flow rate, the range of damage will shrink. Besides, this study builds a hot model of steelmaking which simulated the real condition of bottom-blowing steelmaking. Besides the difference between liquid iron properties and water model, this study also considers the influence caused by the bottom-blowing-gas expanding by the heat after it enters the liquid iron. This study also finds that the range of damage of hot model bottom-blowing can reach to 12 times in tuyere diameter. The result of the simulation also indicated that the range of damage shrinks when the flow rate grows. When the flow rate grows to where the damage range is reduced, the degree of damage at the intermediate position still increases as the flow rate grows. The simulation result of a hot model can offer a reference to the flow rate of the converterâs bottom-blowing steelmaking. The simulation result of a hot model also can extend the using time of the converter by avoiding the flow range which causes strong damages, so it is helpful to enhance the efficiency of converterâs operation and reduce the cost of steelmaking.

▼ Microfluidics emerged during the early 1990s with channel networks in silicon or glass. Microprocessing of these materials is labor-intensive and time-consuming, it requires sophisticated equipment in a clean room, and often involves hazardous chemicals. The subsequent use of polymer greatly simplified the fabrication of microchips and led to the rapid development of the field. Polymer such as poly(dimethylsiloxane) (PDMS), has other attractive properties, such as being elastic (easy to make efficient microvalves), permeable to gases, and compatible with culturing biological cells. Despite these advantages, applications of PDMS chips are severely limited by a few drawbacks that are inherent to this material: (i) strong adsorption of molecules, particularly large biomolecules, onto its surface; (ii) absorption of nonpolar and weakly polar molecules into PDMS bulk; (iii) leaching of small molecules from PDMS bulk into solutions; and (iv) incompatibility with organic solvents. To overcome all these problems, Teflon plastics seem to be the perfect solution. They are well-known for their superior inertness to almost all chemicals and all solvents; they also show excellent resistance to molecular adsorption and molecule leaching from the polymer bulk to solutions. However, Teflon has a high chemical inertness of the surface, which is restricted the bonding temperature (>260Â°C).It is not conducive to the low-temperature packaging process. This study presents a simple and rapid process for sealing Teflon-based microfluidic chip at a temperature of 140 °C which is lower than typical bonding temperature of 260 °C. A simple ammonium plasma treatment is used to enhance the surface energy of Teflon substrates such that the bonding temperature can be greatly reduced. Results indicate that the ammonium plasma treated Teflon substrates can be sealed using hot press bonding at a temperature of 140 °C for 20 min. The measured iv bonding strength for the Teflon-based microfluidic devices is higher than those bonded at a reported temperature of 260 °C for 60 min. It shows the measured contact angle for the Teflon substrates treated with different plasmas. Results indicated that the ammonium hydroxide plasma exhibited the best wettability property and the contact angle reached the minimum value of 45o after 5 min of treatment. The ESCA analysis showed the best Defluorination by ammonium plasma. The fluorine/carbon atomic ratio degraded from 1.96 to 1.10 by 5 minutes. The measured bonding strength for the Teflon substrates bonded with different surface activation protocols. Results showed that the bonding strength was enhanced upto 93% after the plasma treatment. The plasma treatment not only enhanced the bonding strength but also reduced the bonding temperature and time. The measured surface roughness only increased 15Â±5 nm (Ra) after the plasma treatment, which is acceptable for most applications in microfluidic systems.

▼ In this study, the dissolution of carbon particle in liquid iron was simulated in the two-dimensional model with axisymmetric assumption. The laminar model and the single-phase-porous-media model were used to simulate the dissolution, and the carbon dissolution rate was dictated by the mass diffusion rate. Comparisons of the results with related references have found similar trend at low Re number. In order to understand the effects of various geometries on dissolution, the particle-shape evolution under the specific flow fields was observed. From the simulation results, the rate of carbon dissolution at high Re number was affected by the recirculation zone, and at low Re number the dissolution rate was depended on the magnitude of contact area between carbon particles and liquid iron. In addition, the dual-sphere carbon model was established to investigate the effect of sphere distance. It is found that the carbon concentration in the recirculation zone hinders the dissolution rate of the downstream sphere at low Re and in neighboring place, and it gradually developed into an ellipsoidal shape. At farther place, the upstream field has relatively little effect on downstream spheres. The sphere developed into a bullet type. At both of neighboring place and farther place at high Re, the sphere developed into a cone shape, and the reasons are related to the generation of recirculation zone and the carbon concentration. This study further investigated the effect of sphere size on dissolution. The sphere space and flow field were fixed in this study, and the dissolution trend was analyzed. At low Re, the particle size of the downstream sphere was fixed and the particle size of the upstream sphere continued to increase, and it needed more time to dissolve not only at neighboring place but also at farther place. The upstream sphere completed the dissolution first, and the same situation can be observed at high Re. However, when the particle size of the upstream sphere was fixed and the diameter of the downstream sphere was changed, the specific particle size can dissolve in the same time. If the downstream particle size further increases, it has to spend more time to dissolve.

▼ Steelmaking is a polluting industry, and its process will produce a lot of smoke containing exhaust gas and heavy metal dust particles. If it is not properly handled, it will cause great harm to the environment. The most important recovery method is the dust collection system. Most of the polluting gases and toxic dust can be collected by a combination of dust collection and secondary dust collection. However, the dust collection system design of some steelmaking plants is not perfect. How much dust scattered outside the factory is one of the key tasks that need to be clarified. This study focuses on the establishment of a geometric model of the 3D EAF building to simulate exhaust gas and dust flow in the plant during the feeding and refining periods. In the study, a set of operating conditions will be fixed, and the effects of exhaust gas flow rate, secondary dust collection flow rate, and exhaust gas initial temperature on the total exhaust gas emission rate will be discussed separately, and transient trajectory particles will be used to describe the trajectories of metal dust particles. The results show that the secondary dust collection in the electric furnace plant is too far away from the furnace mouth. As the exhaust gas rises, it will mix with the cold air and cause the exhaust gas concentration to decrease, the dust collection efficiency is not high. In the case of feeding, the concentration of exhaust gas accumulated on the top of the plant will become higher, and the exhaust gas emission rate will be more than when the bucket is not poured. In addition, the dust will accumulate in the dust collecting hood. When the accumulation density is increased until the secondary dust collection cannot be instantaneously taken away, it will begin to spread around. Diffused dust will have a diameter particle size distribution in the factory due to different terminal speeds. Dust particles larger than 40Î¼m will settle first, and dust particles smaller than 20Î¼m will float on the top of the plant for the longest time. In operation condition, increasing the secondary dust collecting air volume can effectively improve the dust and exhaust gas emission.

▼ This study successfully established a water-model experiment to investigate the solid accretion on the tip of the double bottom-blowing tuyere. This study observes the effects of different parameters on the type and size of the solid accretion. In the experiment, the outer and inner tubes respectively blow gases of normal temperature and extremely low temperature to simulate oxygen-exothermic and hydrocarbon-gas-endothermic reaction. This study changes the operating conditions, including water temperature, gas flow and material for experiment. It is found that, the shape of solid accretion is hemispherical. The solid accretion can protect the bottom of the furnace from back-attack and contacting with liquid. Furthermore, in the solid accretion, a lot of small channels are above the outer tube and a main waterway is above the inner tube. The gases from the outer and inner tube are separated by the solid accretion and the structure of the solid accretion is similar to the schematic from existing document. The experiment operation was varied to understand the effects on the solid accretion. It is found that the solid accretionâs size increases when water temperature drops, outer gas flow rate increases, and inner gas flow rate decreases. In addition, according to the heat-transfer analysis, the material with good thermal conductivity contributes to the increase of solid accretionâs size and stable growth. Furthermore, the gas flow rates were varied to understand the effects on the solid accretion. It is found that in accordance with pressure change, the formation of accretion can be divided into three types: 1. the pressure is stable and the size of solid accretion depends on cooling capacity; 2. the pressure continues to increase and the gas flow is blocked by the solid accretion; 3. the pressure is oscillating and the solid accretion on the top of inner tube forms and disappears alternately. As a result, the pressure pattern curve with these three types can be a reference.

▼ This research presents a detection scheme for analyzing the temperature distribution produced by the Joule heating effect nearby the channel wall in a microfluidic chip utilizing a temperature-dependent fluorescence dye. An advanced optical microscope systemâtotal internal reflection fluorescence microscope (TIRFM) is used for measuring the temperature distribution on the inner channel wall at the point of electroosmotic flow in an electrokinetically driven microfluidic chip. In order to meet the short working distance of the objective-type TIRFM, microscope cover glass are used to fabricate the microfluidic chips. The short fluorescence excitation depth from a TIRFM makes the intensity information obtained is not sensitive to the channel depth variation which ususally biases the measured results while using conventional epi-fluorescence microscope (Epi-FM). Therefore, a TIRFM can precisely describe the temperature profile of the distance within hundreds of nanometer of the channel wall where consists of the Stern layer and the diffusion layer for an electrokinetic microfluidic system. In order to investigate the temperature distribution produced by the Joule heating effect for electrokinetically driven microchips, this study not only measures the temperature on the microchannel wall by the proposed TIRFM but also measures the temperature inside the microchannel by an Epi-FM. In addition, this research presents a method to reduce the Joule heating effect and enhance the separation efficiency of DNA biosamples in a chip-based capillary electrophoresis (CE) system utilizing pulse DC electric fields. Since the average power consumption is reduced by the pulse electric fields, the Joule heating effect can be significantly reduced. Results indicate the proposed TIRFM method provides higher measurement sensitivity over the Epi-FM method. Significant temperature difference along the channel depth measured by TIRFM and Epi-FM is experimentally observed. In addition, the measured wall temperature distributions can be the boundary conditions for numerical investigation into the Joule heating effect. The proposed method gives a precise temperature profile of microfluidic channels and shows the substantial impact on developing a simulation model for precisely predicting the Joule heating effect in microfluidic chips. Moreover, in the research of reducing the Joule heating effect and enhancing the separation efficiency in a chip-based CE system utilizing pulse electric fields, the experimental and numerical investigations commence by separating a mixed sample comprising two fluoresceins with virtually identical physical properties. The separation level is approximately 2.1 times higher than that achieved using a conventional DC electric field. The performance of the proposed method is further evaluated by separating a DNA sample of Hae III digested Î¦Xâ174 ladder. Results indicate the separation level of the two neighboring peaks of 5a (271 bp) and 5b (281 bp) in the DNA ladder is as high as 120% which is difficult to be achieved… Advisors/Committee Members: Lung-Ming Fu (chair), Che-Hsin Lin (committee member), Chia-Yen Lee (chair), Hsiung%20Tsai%22%29&pagesize-30">Chien-Hsiung Tsai (chair), Chih-Yung Wen (chair), Ruey-Jen Yang (chair).
