Gas Turbine Regenerators: A Method for Selecting the Optimum Plate-Finned Surface Pair for Minimum Core Volume

Abstract

Based on a power law curve fit for the Soland et al. 2 modification of the Kays-London 1 way of presenting heat exchanger performance, a closed-form for sizing counterflow regenerators is derived. After applying this method to many Kays-London plate-finned surfaces, the optimum surface pair for minimum heat exchanger core volume is found to be 1/9-24.12 and 1/10-19.35. In general, the minimum core volume will be obtained by following a three step process: 1) select a surface for the high pressure side having the minimum plate spacing commensurate with cleaning constraints; 2) list all other available surfaces with plate spacings nearly equal to the selected high pressure side plate spacing; 3) select from this list the surface with the minimum hydraulic diameter for use on the low pressure side. Keywords: Gas turbine regenerators.
