| Outline of Final Research Achievements |
A new steam engine cycle for which flash evaporation and wall heat transfer are used as an exhaust heat recovery system was proposed. A flash steam engine was made and the influence of the temperature of the pressurized water at elevated temperatures and the wall temperature, on thermal efficiency of an engine was investigated quantitatively. The flash vaporization process was visualized later, and a system where the spray angle and the spray tip penetration can be measured was built. After the start of injection the nozzle temperature was seem to decrease, and it was found that the spray becomes unstable even if the injected water temperature is kept constantly.
