摘要：The finite time exergoeconomic performance optimization of a generalized irreversible thermoacoustic cooler with heat resistance, heat leakage, relaxation effect, and internal dissipation, in which heat transfer between the working fluid and heat reservoirs obeys a complex generalized heat transfer law (Q proportional delta (Tⁿ)), where n is a complex heat transfer exponent, is investigated in this paper. Both the real part and the imaginary part of the complex heat transfer exponent change the optimal profit rate versus the coefficient of performance (COP) relationship quantitatively. The operation of the generalized irreversible thermoacoustic cooler is viewed as a production process with exergy as its output. The finite time exergoeconomic performance optimization of the generalized irreversible thermoacoustic cooler is performed by taking profit rate as the objective. The analytical formulae about the profit rate and the COP of the thermoacoustic cooler are derived. Furthermore, the comparative analysis of the influences of various factors on the relationship between optimal profit rate and the COP of the generalized irreversible thermoacoustic cooler is carried out by detailed numerical examples. The optimal zone on the performance of the thermoacoustic cooler is obtained.
