3D engineered capillary evaporators for enhanced critical heat flux and heat transfer coefficient in pool boiling and vapor chamber
Nasersharifi, Yahya (Wichita State University, 2020-07)A major challenge in pool-boiling heat transfer lies in the limit of the Critical Heat Flux (CHF) and Heat Transfer Coefficient (HTC), which is caused by the poor counterflow of liquid and vapor over a heated surface, ... -
Adsorption and capillary transition-controlled thermal diodes and switches using heterogeneous nanostructures
Avanessian, Tadeh (Wichita State University, 2017-12)Thermal diodes and switches are systems that enable us to control thermal transport, preferentially in one direction, and switch "on"/"off" on demand. The main challenges of existing thermal diodes and switches are poor ... -
Enhanced two-phase cooling using bi-particle-size sintered particle evaporator with distributed liquid supply capillary wicks
Egbo, Munonyedi Kelvin (Wichita State University, 2021-08)Liquid-vapor, phase-change heat transfer using wicks can provide reliable and high heat flux cooling capability, especially in microgravity applications. However, the maximum heat removal capacity, also known as Critical ... -
Optimal design of capillary-wick for high heat flux thermal management system
Tarafder, Kapot Kallol (Wichita State University, 2015-05)A thermal management system for high heat flux is in great demand as the device sizes become smaller. A failure of the optimal thermal management leads to poor performance, large degradation, and/or complete system breakdown. ... -
Proton conductivity of graphene-based Nafion® catalyst layer for polymer electrolyte membrane fuel cell
Khan, Aamer (Wichita State University, 2015-07)Polymer Electrolyte Membrane Fuel Cells (PEMFCs) are the most assuring alternative power sources for a clean energy/environmental future, however, performance needs to be improved for large-scale commercialization. One of ...
