Heat and Mass Transfer Modeling and Experimental Validation of a Novel Freeze Desalination Process
Freeze concentration is a thermal separation process that is used to purify aqueous solutions. One application of recent interest is seawater desalination. For freeze concentration to be an effective desalination method, a high ice growth rate and product purity must be achieved with energy usage …

Investigations into Message Passing Neural Networks and Polymer Fouling
… and operation. A few challenges include reduced thermal separation efficiencies and increased process safety concerns. Identifying the root causes to various forms of process fouling is essential to identifying the appropriate mitigation strategies. In particular, polymer fouling within ethylene …

Experimental investigation of vortex tube and vortex nozzle for applications in air-conditioning, refrigeration, and heat pump systems
… cooling cycles has been examined. Vortex tube thermal separation performance for air, R134a and carbon dioxide is provided. It has been found that when using single-phase vapor as the working fluid the vortex tube cold end temperature can always be lower than the isenthalpic expansion …

VOC Interference with Standard Diesel Particulate Analysis for Mine Samples: Exploring Sources and Possible Solutions
… filter then measurement of POC and EC using a thermal-optical analysis. Error in DPM measurement occurs when volatile organic carbon (VOC) sorbs onto the particulate matter deposit and filter resulting in a positive sampling artifact. To correct for this, a dynamic blank method with two quartz …

Design and Modeling of Nanostructured Palladium-Based Hydrogen-Selective Membranes
… are projected to grow exponentially, making the separation of hydrogen from other gases a critical step in meeting some of these growing needs. This thesis focuses on the separation needs for nuclear fusion and decalin dehydrogenation. Nuclear fusion reactors such as the one being developed by …
