Abstract
Abstract An equation for the core volume of two-fluid, flat plate, plate fin heat exchangers is put into closed form by using empirical relationships between j Re and f Re3. Fin effectiveness is included, and different core types may be used on the two sides of the exchanger. Although the equation cannot be solved explicitly, the results of an implicit solution for cross-flow cores may be plotted as volume/UA, with pumping power/UA on each side as independent variables. Using an additional fit of) versus Re, face area/flow for each side can be mapped on the same cross-flow plot, and plots for counterflow made. Such plots are useful for quickly indicating the relative volumes and shape of different core types for a given application and for system trade-off studies.
