1. DiPaola, Christopher, 1996-. Design, fabrication, and control of an autonomous sorting system for non-ferrous metal recycling.

Degree: MS, Mechanical and Aerospace Engineering, 2019, Rutgers University

Autonomous sorting systems are applied to pure and heterogeneous types of metallic materials for recycling purposes with goals of efficiency in mind. The purpose of this work was design and build an adjustable, automated, conveyor included sorting system, and validate and evaluate its function and performance for sorting copper and aluminum pieces in experiments. An overview of sorting methods in recycling, mining and other industries are provided to examine the choices made in the design this system. Fabrication steps were taken with facility factors in mind to build and mount the individual components of the system. Challenges faced in the fabrication and operations of the system are also considered. Individual components including compressed air, IR detection, and computer controls are integrated together into the final system. Demonstrations of the system components is done for each component separately, and then merged to form the finalized system. The design features the use of IR sensors to identify a variety of non-uniform copper and aluminum pieces quickly, an array of relays to open manifold outlets automatically, twenty solenoid valves with compressed air actuation for timely control of air flow, and a computer-based data acquisition system for real-time sensing and control under MATLAB-Simulink real-time software environment. Safety features are added to the system so that accidents can be prevented while utilizing the industrial components. This setup is built successfully and met the design expectation. Experimental implementation to sort the copper and aluminum particles (each ranging from 0.5in to 1in wide) shows that the system is very useful at detecting and shooting materials at speeds from 15-45cm/s. This setup provides the capability to implement the same methods industry uses and has the flexibility for prototyping future applications. The experimental results show non-ferrous metal pieces can be successfully identified and sorted.

2. Wang, Hanxiong, 1989-. Energy materials: modeling, design and applications of electrowetting, thermoelectric and superconducting materials.

Degree: PhD, Mechanical and Aerospace Engineering, 2019, Rutgers University

Energy materials play a significant role in modern material science. To understand the mechanism of functional materials, an energy functional formulation method can provide an efficient way to systematically describe the behavior of energy materials. Energy formulation method also has the advantage in dealing with the difficulties in the field formulation. In this thesis, we mainly have three parts of work based on energy formulation method. First, an interesting problem on the equilibrium shape of a bubble/droplet in an electric field is investigated. This is important for electrowetting over dielectrics (EWOD), electrohydrodynamic enhancement for heat transfer, and electro-deformation of a single biological cell among others. In this part of work, we develop a general variational formulation on account of electro-mechanical couplings. In the context of electrohydrodynamics (EHD), we identify the free energy functional and the associated energy minimization problem that determines the equilibrium shape of a bubble in an electric field. Based on this variational formulation, we implement a fixed mesh level-set gradient method for computing the equilibrium shapes. This numerical scheme is efficient and validated by comparing with analytical solutions at the absence of electric field and experimental results at the presence of electric field. We also present simulation results for zero gravity which will be useful for space applications. The variational formulation and numerical scheme are anticipated to have broad applications in areas of EWOD, EHD, and electro-deformation in biomechanics. Secondly, based on the continuum theory of thermoelectric materials developed by Liu[71], we predict that the power factor of thermoelectric (TE) composites can be significantly enhanced by simple laminate structures. This prediction is numerically verified by the Finite Element Model (FEM) that is implemented to compute the local fields in heterogeneous TE structures of general geometries and boundary conditions. Among many other applications, the FEM enables to investigate the effects of small electrical contact on power generation. For a cylindrical sandwich TE structure, we show that the power output of the TE sandwich structure, though lowered by a small contact area, is still significantly larger than that of the constituent TE semiconductor. Thirdly, we study the type II superconducting materials. Many applications of high-temperature superconductors(HTS) need a high critical current density Jc, especially under a strong external magnetic field. An effective way to enhance Jc is to pin the vortex array to avoid flux flow. Therefore, fluxing pinning plays an important role in the properties of HTS. Here, based on Ginzburg- Landau theory and classic Landau theory of micromagnetics, we formulate the total free energy of the system associated with superconducting materials coupling with paramagnetic inhomogeneities. Consider thin film scenario, pinning force which is related to the size of inhomogeneity, paramagnetic… Advisors/Committee Members: Liu, Liping (chair), NORRIS, ANDREW (internal member), Mazzeo, Aaron (internal member), Han, Zheng-Chao (outside member), School of Graduate Studies.
