Abstract

The depletion and high level of pollution caused by fuel are the main reason for today’s search and pursuit for an alternative energy source and an efficient engine cycle. Stirling engine (SE) cycle is deemed to meet the demand required. SE. SE has design and mechanical simplicity yet complex thermodynamics operation. This paper studies on the thermodynamics behavior of the Alpha type Stirling engine (ASE). A Computational Aided Engineering (CAE) analysis was performed to predict the thermodynamics behavior of the ASE. The CAE analysis was conducted with the phase angle,  of 90° between the two pistons of ASE. The results of the analysis in terms pressure, volume, temperature and trapped mass over the crank angle were presented. It was concluded that the thermodynamics performance and behaviour of an ASE are highly dependent on its geometrical design.
