Numerical Simulation of Flow and Heat Transfer Characteristics Focused on Gas-Liquid Two-Phase Flow Case in Core Simulator of MIPR

National Key Laboratory of Reactor System Design Technology, Nuclear Power Institute of China, Chengdu, 610041, China

摘要: 针对医用同位素生产堆(MIPR)堆芯试验模拟体气-液两相试验工况,选取模拟体的1/20作为计算对象,采用非结构化网格方法进行模型网格划分,运用CFD技术进行数值模拟计算研究,同时,对其流场、温度场分布状况及传热特性等进行了分析。计算结果与试验结果的比较分析表明,两者吻合较好。

Abstract: In this paper,the CFD technique is used to conduct the numerical simulation study which aims at a body of 1/20 of the core simulator of the Medical Isotopes Production Reactor （MIPR）,and non-fabric gridding is adopted to compartmentalize the model to study the gas-liquid two-phase flow case.The flow field,temperature field and heat transfer characteristics are analyzed as well.The comparison results show a good agreement between the computation and the experimental results.
