The performance of multi-parallel-passage heat exchangers can be degraded by failure to distribute each fluid evenly among its passages and by failure to optimize the passage arrangement. The effects of maldistribution are particularly severe in exchangers containing large numbers of transfer units and are a major concern for the designer of cryogenic exchangers. This presentation describes a method which has been used to simulate coil-wound and plate-fin exchanger performance and presents the results of applying this method to some selected exchanger configurations.
