Carbon Foam Cold Head Heat Exchanger For O2 Liquefaction
NASA proposed to develop a cryogenic system which incorporates integrated refrigeration with a Brayton cycle to liquefy and store oxygen for a sustainable consumables transfer station for use on the lunar surface. For this cryogenic system to be compact and lightweight, a very significant enhancement in gas side heat transfer coefficient is required. In this paper, heat transfer and pressure drop with carbon foam as a heat transfer medium was investigated both experimentally and numerically. It was demonstrated that porous carbon foam is very effective in increasing heat transfer but can also lead to a high pressure drop. With a corrugated configuration for the carbon foam, pressure drop can be significantly decreased without an appreciable change in heat transfer coefficient.
