Design and Development of Low Temperature Zero Watt Alpha Type Stirling Engine

The design and development of a low temperature alpha type Stirling engine is to be conducted. The design criterion for the engine is to produce about 10 Watts of power at 60 rpm or about 10 Joules per cycle. An 80K temperature difference is assumed with an input temperature of 380K and an output te...
