H-MATRIX DESCRIPTION OF THE PERFORMANCE OF REGENERATOR

Basing on the active network modeling approach for regenerative heat engine, it is proposed that the energy conversion effect in regenerator can be modeled by analogy with transistor amplifier circuit. Following the method of network analysis, it is demonstrated that the thermoacoustic source term for a real regenerator in regenerative heat engine system can be identified experimentally with regenerator in system working under operational conditions. A performance description method for regenerator in regenerative heat engine system is proposed in the paper.
