A Liquid–Vapor Two-Phase Model of Direct Methanol Fuel Cells With Platinum Group Metal-Free Cathode Catalyst
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study has developed a two-dimensional, two-phase transport model to investigate the transport characteristics in direct methanol fuel cells (DMFCs) using platinum group metal (PGM)-free cathode catalysts. The model ...
Condensation of R134a and R22 in Shell and Tube Condensers Mounted With High-Density Low-Fin Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, the condensation of refrigerants on a single, high-density, low-fin tube and full-sized shell and tube condensers were investigated experimentally. The low-fin tube had an external fin density of 56 fins per ...
