A08 Results obtained though a new regenerator performance instrument

Abstract

A new method to measure heat transfer between the working gas and the regenerator matrix has been proposed in the previous work. Since the change in internal energy of working gas is calculated from its pressure and volume, heat added to the working gas can be estimated from the 1st law of thermodynamics with measured pressure history. Measurements were carried out for various combinations of changing the stroke, phase difference and frequency of the pistons. The results have been correlated in a dimensionless with three independent variables.
