Thermodynamic Optimization of Stirling Heat Engine With Methane Gas Using Finite Speed Thermodynamic Model

With day by day increasing of pollution due to using of conventional fuels, and other environmental issues motivates us to the usage of renewable energy sources. Stirling engine is the one of the power generation unit which can be works on the waste heat or low temperature differential energy resources and it works based on the regeneration and waste heat recovery principle. Still, there is potential in the improvement of performance of the Stirling engine. Performance of Stirling engine can be improved by finding out the desirable operating and geometrical parameters for the applied different types of thermal models as well as for applied different working fluids in Stirling engine. In this paper, Stirling heat engine with Finite Speed Thermodynamic model and working fluid is methane gas is taken here for multi objective optimization. The effect of different decision variable is considered for the analysis of power output and pressure drop. Multi-objective heat transfer search (MOHTS) algorithm is used and checked out for the multi-objective optimization of Stirling engine. With two objective maximization of power output and minimization the pressure drops the optimization of Stirling heat engine is done
