摘要

摘要: 分别对出口直径为6、8、10 mm的喷嘴,入口压力为0.2-0.6 MPa的饱和蒸汽在过冷度为40-80℃的水中形成的音速蒸汽浸没射流凝结的轴向全压分布特性进行实验研究,得到蒸汽压力、过冷度和喷嘴出口直径对轴向全压的影响规律。针对轴向全压大于入口蒸汽压力这一现象,得到峰值压力以及峰值压力出现位置随蒸汽压力、过冷度和喷嘴尺寸的变化规律。实验结果表明,在低压下喷嘴出口直径对压力峰值特性影响较大,而在高压时上述影响很小;根据其影响因素,得到用于预测轴向全压无量纲峰值距离的实验关系式,预测结果与实验值吻合较好,误差在±15%以内。

Abstract: The axial total pressure distributions of sonic steam jet in subcooled water were experimentally investigated for three different nozzle diameters（6.0mm,8.0mm and 10.0mm）.The inlet steam pressure,and pool subcooling subcooled water temperature were in the range of 0.2-0.6MPa and 420-860℃,respectively.The effect of steam pressure,subcooling water temperature and nozzle size on the axial pressure distributions were obtained,and also the characteristics of the maximum pressure and its position were studied.The results indicated that the characteristics of the maximum pressure were influenced by the nozzle size for low steam pressure,but the influence could be ignored for high steam pressure.Moreover,a correlation was given to correlate the position of the maximum pressure based on steam pressure and subcooling water temperature,and the discrepancies of predictions and experiments are within ±15%.
