Stirling engine is a closed-cycle regenerative heat engine, wherein the working fluid is permanently confined within the system. The working fluid is gaseous in nature. Stirling engine works by the cyclic compression and expansion of the gas inside a cylinder, which leads to the generation of heat inside the heat engine. The heat generated is then converted to mechanical work by pushing a piston. There are three types of stirling engines: the alpha type, the beta type, and the gamma type. ... Read more
