An Experimental Investigation of Drag Characteristic of A Hot Particle Moving in Coolant Liquid
-
摘要: 通过实验,研究了高温小球在冷却剂中的运动阻力特性,揭示出高温难挥发的熔融物与低温易 挥发的冷却剂相互作用的粗混合阶段具有特殊结构高温熔融金属液滴在冷却剂中的运动规律。研究结果对于 开发多成分多相分析程序和研究核电站严重事故中燃料与冷却剂的相互作用具有重要意义。Abstract: The movement characteristic of a hot particle moving in coolant liquid is experimentally studied in this paper, it shows the movement rules of the hot particle with such specific configuration in coolant liquid, in the coarse premixing phase of interaction between hot molten particle and volatile coolant liquid. The results are significant to the development of multi-phase multi-component analysis procedure and the research of FCIs in severe accidents of reactors.
