Influence of heat in-leak, longitudinal conduction and property variations on the performance of cryogenic plate-fin heat exchangers based on distributed parameter model

Influence of heat in-leak, longitudinal conduction and property variations on the performance of cryogenic plate-fin heat exchangers based on distributed parameter model

For helium liquefaction/refrigeration systems, conventional design theory always fails in cryogenic applications and heat exchangers operating at low temperatures are usually sensitive to longitudinal heat conduction, heat in-leak from surroundings and variable fluid properties. Governing equations...
