摘要
采用21根束棒元件研究系统压力对再淹没传热的影响。试验参数范围为:系统压力为0.1—0.4MPa,入口淹没率为14.5—39.5mm·s^(-1),加热功率为0-0.116kW·m^(-1),初始壁温为380—540℃,入口水温为25-40℃。实验结果表明:再湿速度、传热系数和骤冷温度随系统压力的增加而增加。
Experiments are performed for investigating the effect of system pressure on reflooding heat trans-fer. The test section is a rod boundle with 21 rods. The test parameter is in the range of 0.1--0.4 MPafor system pressure, 14.5--39.5mm·s^(-1) for inlet reflood flow rate, 0--0.116kW·m^(-1) for heatingpower, 380--540℃ for initial wall temperature and 25--40℃ for inlet temperature, respectively. Theexperimental results show that rewetting velocity is increased, heat transfer coefficient and guench tem-perature are all increased with system pressure.
