FLASHING AND SHATTERING PHENOMENA OF SUPERHEATED LIQUID JETS

Depending on the preset conditions, a flashing liquid jet can either s hatter or remain in the form of an irregular continuous column after b eing released from the nozzle to the flashing chamber. Four physical c haracteristics of a flashing liquid jet in the field of low pressure h ave been unveiled, namely, non shattering liquid jet, partially shatte ring liquid jet, completely shattering liquid jet but in stagewise seq uence and flare flashing liquid jet. Temperature distribution of the l iquid jet along the axial direction is determined to be exponential an d varies according to the liquid jet type. Other analyzed characterist ic trends include radial temperature distribution of the liquid jet, d roplet size distribution and volumetric flowrate distribution in the d ispersed jet. In addition, the contribution of bubble nucleation and g rowth to the liquid jet shattering in the field of low absolute pressu re is hereby made clear.
