Abstract

This study investigates anti-icing design by conjugate heat transfer analysis in lab-scale printed circuit heat exchanger (PCHE) for supply of cryogenic high pressure liquid hydrogen. The conjugate heat transfer analysis by using computational dynamics (CFD) provided various temperature distributions at important locations in PCHE heat exchanger and predicted the possibility of freezing in hot channel. And, the effect of inlet temperature of glycol water was analyzed in order to resolve the freezing problem in PCHE.
