Description
This study examines the angular velocity of a horizontal γ-type Stirling engine with a slider-crank mechanism during startup. The aim is to exclusively utilize thermal energy as the sole source of power to operate the Stirling engine. The engine was tested using air as the working fluid. In the experimental setup, a band heater and a gas torch provided heat input, while an intercooler handled heat rejection. The results indicated that when using both a gas torch and an intercooler, the angular velocity was 235 rpm, compared to 258 rpm when using only a gas torch without an intercooler. It was observed that the intercooler did not result in a significant temperature difference when the γ-type Stirling engine was in operation. Additionally, the impact of the working gas at a minimum temperature of 250°C on the band heater led to the engine operating at 242 rpm for starting engine. The highest angular velocity recorded was 352 rpm at a temperature of 400°C. The γ-type Stirling engine is available with low temperature differences, but the shaft work output is low.
