Numerical Simulation of a Double-Acting Stirling Engine in Adiabatic Conditions

Abstract:

This paper is aimed at development of a numerical model for a double-acting Stirling engine in adiabatic conditions. By taking into account the ideal and non-ideal adiabatic conditions, the periodic variation of pressures, volumes, temperatures, masses, and heat transfers in the expansion and compression spaces are predicted. And the power output and overall efficiency on the geometrical and physical parameters of the General Motors 4L23 with the numerical model have been validated, the results calculated by the model are close to the tested data. The heat conduction loss of the piston wall, shuttle loss of the piston and the leakage of operating gas have not been taken into account, so the calculated value with non-ideal adiabatic model is slightly higher than the tested value of the prototype engine.
