The thermodynamic cycle of a gas parcel in the thermo-acoustic engine is referred to as a thermo-acoustic micro-cycle, which consists of two isobaric branches by two straight line branches. The influence of quantum degeneracy on the work output of the cycle is investigated based on the...

The operation of a universal steady-flow endoreversible refrigeration cycle model consisting of a constant thermal-capacity heating branch, a constant thermal-capacity cooling branch and two adiabatic branches is viewed as a production process with exergy as its output. The finite-time...

Ecological performance optimization of a generalized irreversible thermoacoustic cooler with heat resistance, heat leakage, thermal relaxation and internal dissipation, in which heat transfer between the working fluid and heat reservoirs obeys a complex generalized heat transfer law <inline-formula><inline-graphic xlink:href="ctp038ileq1" xmlns:xlink="http://www.w3.org/1999/xlink"/></inline-formula>, where n is...

A new model consisting of two isobaric branches connected by two straight-line branches is established to investigate the thermodynamic performance of a thermoacoustic refrigeration micro-cycle. The influence of quantum degeneracy on the dimensionless cooling load R* of the cycle is analysed...
