Abstract:
When overheated liquid is depressurized rapidly and the internal temperature is above the saturation temperature under the final condition, the meta-stable liquid will change toward its new equilibrium condition through violent evaporation. It is so called flashing of overheated liquid. Flashing jet occurs when overheated liquid sprays into vacuum through a nozzle. It results in jet propulsion when a fraction of liquid is vaporized rapidly and two-phase flow is formed. This propulsion technology is successfully applied to the propulsion system of the accompanying satellite.
