ON THE CHARACTERISTIC PROPERTIES OF COMPRESSIBLE SPRAY-TYPE TWO-PHASE (GAS-LIQUID) FLUID AND ITS MEASURING TECHNIQUE

For developing the jet cutting technology which uses the high speed liquid jet having a velocity of high Mach numbers compared with air, it would seem to be important to consider the results of an investigation on the internal mechanism of a high speed liquid jet. The theoretical treatment of compressibility relating to this spray-type two-phase (gas-liquid) fluid flow which is composed in part of a high speed liquid jet is examined and the results of measurements relating to the simulated liquid jet based on the theoretical treatment is discussed. The high speed liquid jetted from the nozzle forms a spray-type two-type two-phase (gas-liquid) fluid flow mixing with the surrounding air. From the view point of showing the extremely small value of sonic velocity in this fluid flow, the high speed liquid jet which jets out in the air easily becomes the supersonic flow or hypersonic flow. So, in the study of the internal mechanism of a high speed liquid jet, except the non-contact method of measurement, we cannot use the usual method of measurement, but we must therefore develop a new method of measurement applicable to supersonic flow.
