本文在广泛的蒸汽压力和过冷水温度范围内,针对饱和蒸汽通过不同出口直径的喷嘴在过冷水中浸没射流凝结引起的压力冲击特性进行了实验研究,测量得到了不同轴向位置和径向位置的冲击压力,并分析了入口蒸汽压力,过冷水温度和喷嘴出口直径对冲击压力的影响规律。结果表明冲击压力主要受入口蒸汽压力和过冷水温度的影响;同时,当汽水参数以及无量纲轴向和径向距离相同时,不同出口直径的喷嘴对应的冲击压力变化很小,从而表明喷嘴出口直径对压力冲击影响很小。
In this paper, a wide range of steam pressure and supercooled water temperature range, for saturated steam through different nozzle diameter nozzle in subcooled water jet condensation caused by the impact of the pressure of the experimental study measured different axial position and radial position The influence of inlet steam pressure, supercooled water temperature and nozzle outlet diameter on impact pressure was analyzed. The results show that the impact pressure is mainly affected by the inlet steam pressure and the temperature of the supercooled water. At the same time, when the parameters of the soda water and the dimensionless axial and radial distances are the same, the impact pressures of the nozzles with different outlet diameters vary little, Diameter has little effect on the pressure shock.
