A02 Flow and power output characteristics of a Stirling engine

Flow resistance, heat transfer and indicated work were measured for a high performance model Stirling engine. Flow resistance was measured for Stacks of honeycomb plates and of metal gauzes. Flow resistance for honeycomb plate was correlated with Uchida's analytical solution with a 1.2 factor. That for wire gauze was roughly doubled. Compression and expansion were carried out almost adiabatically. Heat transfer in isometric heating and cooling was comparable to that calculated for an isothermal model. In spite of low heat transfer on compression and expansion, indicated work corresponds to that calculated with isothermal model.
