Abstract

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%.
