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...

Based on constructal theory, the disc-shaped solid–gas reactors combined heat and mass transfer are investigated in this paper. Radial- and branched-pattern of the discs are considered, and the two pattern discs are optimized based on entropy generation rate minimization. The results show that...

A performance analysis is performed on the air-standard Diesel cycle using finite-time thermodynamics. The relations between net work and/or power, efficiency, and compression ratio, and the maximum net work and/or power and the corresponding efficiency bound are derived for the cycle with...

The optimization problem of a combined refrigeration cycle formed by two endoreversible Carnot refrigeration cycles in series without intermediate reservoirs has been studied using finite-time thermodynamics. The fundamental relation between cooling quantity and coefficient of performance (COP)...

The performance of an endoreversible regenerative Brayton heat engine has been studied. The analysis is focused on minimizing irreversibilities associated with the hot and cold heat exchangers and regenerator.

A total momentum filtered energy selective electron (ESE) heat pump model with heat leakage is established in this paper. The analytical expressions of heating load and coefficient of performance (COP) for both the total momentum filtered (kr-filtered) ESE heat pump and the conventionally...
