Heat transfer enhancement of a Stirling engine by using fins attachment in an energy recovery system

Compared to other traditional engines, the Stirling engine is an externally closed heat engine loop with a high theoretical efficiency and low emissions. Due to its multi-fuel capacity, including solar, biogas and geothermal energy, this property is now becoming very advantageous. However, the perfo...
