| 摘 要： | 本文通过对MIXA06实验的模拟来研究发生在核反应堆严重事故情况下的燃料与冷却剂相互作用(FCIs)细粒化混合过程.采用基于泰勒不稳定性的水力学细粒化模型,对这种高温熔融物与低温冷却剂接触时的强烈热物理作用过程进行数值计算和预测,研究在低韦伯数条件下水力学细粒化模型的适用性.计算结果和参数敏感性分析结果表明,水力学模型低估了熔融液滴的细粒化率.

| Abstract: | The process of Fuel Coolant Interactions (FCIs) in nuclear reactor severe accident is studied by the simulation of MIXA06 experiment.Numerical works for this violent thermal-physics interaction of high temperature melt with low temperature coolant are carried out to investigate the hydrodynamic fragmentation model which is based on the Taylor Instability,under condition of low Webber numbers. The result shows that hydrodynamic model underestimate the fragmentation rate. |
