INFLUENCE OF WORKING FLUID PRESSURE ON THE POWER OF A STIRLING GAMMA ENGINE
This study aims to highlight the influence of working fluid pressure (fot this application being air) on the power developed by a Stirling gamma engine whose total cylinder capacity is 36.796 cm3. For an experimental determination of power an electric DC motor is used. It operates in the start – up mode (puts into motion the Stirling engine), the electric generator mode – specific for the whole Stirling engine running time and the braking mode when the electric motor is powered by an external power supply and by measuring voltage and electric current absorbed by the electric motor determines the power developed by the Stirling engine. Analytically, the power developed by the Stirling engine is determined by the mathematical models presented in the technical literature.
