Performance evaluation of an irreversible Stirling heat engine cycle

Thermoeconomic optimization and parametric study of an irreversible Stirling heat pump cycle

“…When the irreversibility of heat transfer is considered, these cycles, in general, do not possess the condition of perfect regeneration. It is reasonable to assume that the regenerative loss per cycle is proportional to the temperature difference of the two isothermal processes and is given by (Chen and Schouten, 1999, Kaushik, 1999, Tyagi, 2000, Kaushik and Kumar, 2000, Kaushik and Kumar, 2001, Kaushik, Tyagi and Mohan, 2003,.He, Chen and Wu, 2001, Tyagi, Kaushik and Salhotra, 2002,…”

“…In recent years, a lot of work has been carried out on the cycles (Blank and Wu, 1995, Chen, 1997, Chen and Schouten, 1999, Kaushik, 1999, Tyagi, 2000, Kaushik and Kumar, 2000, Kaushik and Kumar, 2001Kaushik, Tyagi, and Mohan, 2003 using the concept of finite-time thermodynamics (Curzon andAhlborn, 1975, Salamon andNitzan, 1981). Some workers have applied the ecological criteria (He, Chen andWu, 2001, Tyagi, Kaushik andSalhotra, 2002), while others have used the thermoeconomic approach (Sahin, and Kodal, 1999, Kodal, Sahin and Yilmaz, 2000, Sahin and Kodal, 2001, Antar and Zubair, 2001, Bandyopadhyay, Bera and Bhattacharyya, 2001, Kodal, Sahin and Erdil, 2002, Kodal, Sahin, Ekmekci and Yilmaz, 2003, Chen, Tyagi and Wu, 2003, Tyagi, Chen and Kaushik, 2004 based on energy analysis (Mirandola, Stoppato and Tonon, 2000) and exergy analysis (Moorhouse, Hoke and Prendergast, 2002) on different cycles for a typical set of operating conditions.…”

Multi-objective thermo-economic optimization of solar parabolic dish Stirling heat engine with regenerative losses using NSGA-II and decision making

“…Chen et al [4] studied solar driven Stirling heat engine to find out its maximum possible efficiency. Kaushik et al [5][6][7][8] implemented finite time thermodynamic approach on endoreversible [5] and irreversible [6][7][8] Stirling/Ericsson cycles and found that at regenerator effectiveness of one, Stirling heat engine could perform as Carnot heat engine provided both are operating in endoreversible mode. They also found that maximum power output of Ericsson and Stirling engines are independent of heat losses due to regenerator, effectiveness of regenerator and direct heat leak between heat source and heat sink.…”

Thermo-Environmental Analysis and Multi-Objective Optimization of Performance of Ericsson Engine Implementing an Evolutionary Algorithm

“…Tlili investigated the effects of regenerator effectiveness and internal irreversibility on the thermal efficiency of an endoreversible Stirling heat engine at maximum power condition [93]. Kaushik et al [94][95][96][97] studied effects of regeneration and heat transfer of the heat sink and sources on exergy destruction of Stirling and Ericsson engines. Evolutionary algorithms (EA) were originally used throughout the mid-eighties in an effort to unravel the puzzle of this general category [98].…”

“…It is not reasonable to pay no attention to the time of two regeneration progressions when compared with two constant temperature progressions included in the suggested approach. So, via the below equation the regeneration time calculated[94][95][96][97]: between the heat sink and working fluid (L Q ) and the heat released between working fluid and heat source ( H Q ), are calculated via the below equations…”
