根据预设条件，闪蒸液体射流在从喷嘴释放到闪蒸室之后可以破碎或保持不规则连续柱的形式。揭示了低压场闪烁液体射流的4个物理特征，即不破碎液体射流、部分破碎液体射流、完全破碎液体射流（但有阶段性）和闪烁液体射流。液体射流沿轴向沿着的温度分布被确定为指数分布，并且根据液体射流类型而变化。其他分析的特征趋势包括液体射流的径向温度分布、分散射流中的液滴尺寸分布和体积流量分布。此外，本文还阐明了在低绝对压力场中气泡的成核和长大对液体射流破碎的贡献。
Depending on the preset conditions, a flashing liquid jet can either shatter or remain in the form of an irregular continuous column after being released from the nozzle to the flashing chamber. Four physical characteristics of a flashing liquid jet in the field of low pressure have been unveiled, namely, non shattering liquid jet, partially shattering liquid jet, completely shattering liquid jet but in stagewise sequence and flare flashing liquid jet. Temperature distribution of the liquid jet along the axial direction is determined to be exponential and varies according to the liquid jet type. Other analyzed characteristic trends include radial temperature distribution of the liquid jet, droplet size distribution and volumetric flowrate distribution in the dispersed jet. In addition, the contribution of bubble nucleation and growth to the liquid jet shattering in the field of low absolute pressure is hereby made clear.
