摘　　要：针对蒸汽射流与冷却水直接接触冷凝传热效率的问题,采用FLUENT软件对该冷凝过程进行数值模拟,获得蒸汽压力、最大速度、排汽速率及排汽量随时间的变化规律,在所研制的蒸汽排放处理装置上进行蒸汽冷凝试验,结果表明,该装置能提高蒸汽与冷却水的传热速率,缩短蒸汽的冷凝时间。Aiming at the heat transfer efficiency of the steam jet and the cooling water in direct contact condensation,the FLUENT software was used to simulate the condensation process to obtain the steam pressure,maximum speed,exhaust steam rate and exhaust steam volume curve with time.The steam condensation test on the steam discharge treatment device developed by Shanghai Marine Diesel Engine Research Institute showed that the device can increase the heat transfer rate between steam and cooling water and shorten the condensation time of steam.
