Dynamic Response of Bayonet-Type Heat Exchangers : Part 1, Response to Inlet Temperature Changes

Abstract

Bayonet-type heat exchangers are classified into four cases by the flow directions of shell- and tube-side fluids. The transfer functions, relating outlet temperature responses to changes in inlet temperatures of both tube- and shell-side fluids, are obtained for bayonet-type heat exchangers. Numerical examples are presented, and the effects of flow directions on the frequency response are examined. Experiments of frequency response are carried out, and the data are shown to be in good agreement with the theoretical results.
