Abstract


This study aims to investigate the function of a Gamma type Stirling engine, analyzing mainly the influence of the temperature gradient on the angular velocity and power produced by it. To determine the power generated by the engine, the collected data was processed using an algorithm based on the Schmidt theory modeled in Mathcad. The importance of the temperature gradient was also very well highlighted by the increase in maximum angular velocity with over 150 [rpm] when a cooling rib was added. In time, both the angular velocity and the power reach an approximate constant value, the fluctuations appearing due to the fact that the heat source is not an ideal one.

Key words: Stirling engine, Gamma type, temperature, pressure, angular velocity, working fluid, mechanical power, multifuel engine
