The Sizing and Passage Arrangement of Multistream Plate-Fin Heat Exchangers

摘要

A simple and effective method is presented for the sizing and passage apportionment of multistream plate-fin heat exchangers. Methods for passage arrangement are discussed, and it is shown that a symmetric or “mixed” passage arrangement is more efficient than a “segregated” arrangement. A method for assessing the relative merits of various passage arrangements is presented. The use of the methods is illustrated through a worked example.
