Resumen en inglés Global pursuit to meet emergent energy demands necessitates finding simple and cost-effective solutions. A hopeful solution is the application of renewable energy with thermo-mechanical conversion systems such as Stirling engines. Considerable effort is in hand at industry and academia domains to stimulate the development of Stirling technology. Foregoing, this paper focuses on modelling of low temperature difference gamma-type Stirling engine and investigating means of enhancing its performance through integration of Nitinol spring. The CFD models were comprehensively studied, which helped build the foundation of theoretical concept of Stirnol engine. The results reveal that addition of Nitinol Spring enhances the overall efficiency of engine demonstrating affirmative impact of shape memory alloy towards performance output of Stirling engine.
