Stirling Engine Project
Stirling Engine Project report
Abstract: The Stirling engine is an external combustion, closed, cyclic heat engine which works on the Stirling Cycle. A typical Stirling engine consists of two zones which are maintained at different temperatures and a working fluid is shuttled between these regions to extract work. Unlike the conventional engines and steam engines (an external combustion engine), there are no valves and the working fluid never leaves the engine and is used over and over again. The working fluids commonly used are air, hydrogen or helium. Why Stirling engines? You might be wondering why there is much fuss about these engines and yet why so little development has taken place. The greatest attraction this engine offers an engineer is the fact that theoretically it can achieve “CARNOT EFFICIENCY”. The only other cycle that can achieve Carnot efficiency other than the Stirling cycle is the Ericson cycle. More over cleaner energy sources will soon become the norm and the Stirling engine will definitely play a huge role in the revolution due to its flexibility in the way heat can be supplied to the engine. Be it solar energy, geothermal or even a pile of burning garbage can power the engine.
