Doctoral Dissertations
Vanadium redox flow batteries are a promising large-scale energy storage technology, but a number of challenges must be overcome for commercial implementation. At the cell level, mass transport contributes significantly to performance losses, limiting VRFB performance. Therefore, understanding mass transport mechanisms in the electrode is a critical step to mitigating such losses and optimizing VRFBs.
In this study, mass transport mechanisms (e.g. convection, diffusion) are investigated in a VRFB test bed using a strip cell architecture, having 1 cm2 active area. It is found that diffusion-dominated cells have large current gradients; convection-dominated cells have relatively uniform current distribution from …
Libowski: A Numerical Framework For Solving Depletion And Mass Transport In Molten Salt Reactors, Robert Z. Taylor
Libowski: A Numerical Framework For Solving Depletion And Mass Transport In Molten Salt Reactors, Robert Z. Taylor
Doctoral Dissertations
Molten salt reactors (MSRs) are a class of next-generation liquid fueled nuclear reactor which show great promise and industrial interest. With this type of reactor comes great difficulty in many modeling and simulation aspects which are required for design, operational efficiency and regulatory licensing. Solving the set of coupled depletion and mass transport equations required for modeling and simulations of these reactors is of great interest. This manuscript discusses the formulation of a numerical framework for solving the complex set of depletion and mass transport problems in MSRs. This is accomplished by first defining the set of equations that must …
