Flow in the Stirling Regenerator Characterized in Terms of Complex Admittance Part 2: Experimental Investigation

Abstract

Experiments are described that support analysis of the practical Stirling cycle in terms of linear waves. All aspects of the theoretical approach are corroborated, including the incidence of amplitude attenuation and marked phase shift between pressure-time records on either side of the matrix, together with the overriding importance of the dimensionless groups N _MA and N_SG in characterizing these features.
