Abstract
Recently, Stirling engines are emerging as a key device for power conversion of renewable energy or waste energy. Thisstudy develops a LTDSE(Low Temperature Differential Stirling Engine) using a water spray for higher heat transfer andperforms load performance tests for various flow rates and temperatures of hot water spray for variable engine loads emulatedby a mechanical friction device. Internal temperature and pressure, working frequency and inlet and outlet temperature of thesupply water are measured. As a result, the increases in flow rate and temperature of hot water respectively enhance the poweroutput, efficiency and the working frequency, while the increasing engine load leads to decreases in working frequency butincreases in the pressure amplitude. Eventually, it is revealed there exists a maximum shaft power of the test engine.
