振動型蒸気エンジンの性能評価

抄録

Oscillating flow type steam engine is a mechanism to extract the output using the thermal self-excited vibration caused by repeating the fluid is a gas-liquid phase change in the tubules. It is essentially same to the Pop-pop boat engine has been experimentally investigated. In this study, we measured P-V diagram , input power, output power and amount of heat transport to the heater of some rotation speeds, and confirmed that output power was 1.5W under the conditions that rotation speed was 60rpm and the temperatures of heating and cooling sections were 200 and 70℃.
