摘要

. 反应堆安全是反应堆研究的重要组成部分之一,特别是在严重事故中发生熔毁时的适当应对。本研究采用移动粒子半隐式方法模拟了Al、Fe和Pb在高温下的重定位过程,研究了液体在液体间相互作用时的重定位机制。结果表明,达到分层条件,Pb-Al需要0.63秒,Al-Fe和Al-Pb需要1.14秒,Fe-Al需要3秒以上。总体而言,结果表明,两种液体之间的粘度和密度的差异影响了达到分层状态的时间。两种液体的密度差越大,分层过程越快。

Numerical Study on Relocation Process of Al, Fe, and Pb by Using the Moving Particle Semi-Implicit Method During Severe Accident of Reactor
. Reactor safety is one of the essential parts of reactor research, especially to appropriately respond when melts down occurred during a severe accident. In this study, the relocation process of Al, Fe, and Pb was simulated by using the Moving Particle Semi-Implicit method to study the relocation mechanism of the liquids when they experienced an interaction between liquids at high temperatures. It is obtained that, to reach the stratified condition, Pb-Al needs 0.63 seconds, Al-Fe and Al-Pb need 1.14 seconds, and Fe-Al needs more than three seconds. Overall, the results indicate that the difference in viscosity and density between two liquids influences the time to reach the stratified condition. The greater the density difference between two liquids, the faster the stratification process.
