New Method of Evaluating Dynamic Response of Counter-Flow and Parallel-Flow Heat Exchangers.

摘要

From the exact solutions for the frequency response of counter-flow and parallel-flow heat exchangers, successive parameters are calculated which give direct information for the heat exchangers regarding transient responses as well as frequency responses. The numerical evaluations of the parameters from the design data of heat exchangers are generally very simple, although the formulae themselves appear somewhere involved. Good coincidence with measured transient responses is demonstrated on an example. (Author).
