| 摘 要： | 按1:10的比例建立了反应堆压力容器直接安注的试验模型,进行了流动可视化、常温常压下的传热与高温高压下的传热试验,并在试验研究的基础上,利用FLUENT5.4商用软件进行了数值模拟研究。通过研究获得了反应堆压力容器直接安注时的瞬态传热系数、流体的混合函数及瞬态温度的变化规律,为反应堆压力容器在安注时的承压热冲击分析提供了重要的依据。

| Abstract: | A RPV test model on the scale of 1:10 with direct safety injection was established. The experiments of flow visualization, heat transfer at ambient temperature and pressure, and heat transfer at high temperature and pressure were performed. Based on the tests, the numerical simulations by using the commercial fluid dynamic software FLUENT 5.4 were conducted. In the work, the transient heat transfer coefficients, the mixing functions and the transient temperature change of the fluid were determined for the reactor pressure vessel during direct safety injection. The results from the study may be used for the PTS analysis of RPV. |
