“…Stirling engine's thermal efficiency is determined by the ratio of its power output to the amount of heat transferred from high-temperature source. Schmidt developed a model to predict the power output of a Stirling machine [13][14][15]. Furthermore, Chen and Giffin [16] identified 25 different models of Stirling engines.…”

Global pursuit to meet emergent energy demands necessitates finding simple and cost effective solutions. A promising 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 (LTD) gamma-type Stirling engine and investigating means of enhancing its performance through integration of Nitinol spring. The CFD models were comprehensively developed to simulate the engine, which have been subsequently validated through experimental data. 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.

“…The thermal efficiency of any engine is defined as the ratio of the power output to the heat transferred from high-temperature source. The first person to develop a model to predict the power output of a Stirling engine was Schmidt [13][14][15]. Subsequently, Kongtragool [16] proposed the modified Beale number with the following equation:…”

Population explosion, industrialization, and urbanization have accelerated energy requirements across the globe. This has led to the human quest to find simple and cost-effective energy solutions. A promising solution is the revival of the Stirling engine with the addition of Shape Memory Alloy NiTiNOL in it. The experimental results reveal that the addition of a NiTiNOL spring at the base plate of the Stirling engine enhances the overall efficiency of the engine, demonstrating some impact of the shape memory alloy toward the performance output of the Stirling engine. The newly modified engine has been named the STIRNOL ENGINE. The comparative study of Stirling and Stirnol engines reveals a minuscule efficiency improvement, yet there is a furtherance that opens a window for future researchers to get a lead and venture into this new field. We are confident that with more complex designs and better Stirling and NiTiNOL combinations, more efficient engines can be invented in the future. This research focuses on changing the material of the base plate of the Stirnol engine and ascertaining its performance differential through the integration of the NiTiNOL spring. A minimum of four types of materials are utilized for experimentation.
