Analysis of Thermodynamic Modelling for Gamma Type Double Piston Cylinder Engine

The exhaust of an automotive engine is one of the main causesof air pollution. These days, many researchers are investigating the wasteheat recovery of automotive engines. A two-cylinder gamma-type Stirlingengine is chosen for this purpose. The exhaust of a diesel engine is chosenas a heat input source for this purpose. This work explains the isothermal,ideal adiabatic, and non-ideal simple analysis of the Stirling engine. A setof differential equations are solved using Runge-Kutta 4th order methodusing MATLAB software. These equations describe the pressure, pressurevariation, mass, mass flow, and energy flow in the Stirling engine whichestimate the power and efficiency. Using non-ideal simple analysis,pressure drop analysis, piston finite speed, heat transfer losses of Stirlingengine are calculated. The power estimated by isothermal, adiabatic,simple, and experimental analysis is 133.82 W, 143.75 W, 93.2 W, 111.43W, and thermal efficiency is 30.70 %, 30.90%, 21.20%, 24.70%respectively. The results of these models are in close agreement with theexperimental results
