The Influence of the working fluid and Regenerator material on the Performance of the types Gamma Stirling Engine

In concentrated solar energy applications, the Stirling engine is optimum option for extracting mechanical work. The engine's most notable features are minimal noise, vibration, and pollution, as well its capacity to function with any external heat source, including biomass, energy, industrial waste. gamma-type STE-1008 subject of our research. This can handle a maximum charging pressure 10 bar. divided into two sections (expansion compression) three exchangers (regenerator, cooler, heater). cooler finned aluminium exchanger 144 internal fins, each cross-sectional area 1 mm by mm. regenerator fitted diameter 31 m volumetric porosity 90%. investigation employed random fiber different metals: stainless steel, copper, aluminium. Nitrogen air served working fluids. From results, regenerators produced 583 W, 562 553 respectively. When nitrogen utilized at 500 °C, generates 11 N.m torque compared 8.5 when used, has thermal efficiency 19% 15% used. results other researchers were used compare validate model. With errors no more than 12%, close enough experimental data be useful.
