Three-Dimensional Numerical Simulation of Temperature Field and Helium Flow Field in ITER China TBM

Institute of Nuclear Energy and New Energy Technology, Tsinghua University, Beijing, 100084, China

摘要: 采用通用计算流体力学软件Fluent对应用于国际热核实验堆(ITER)的实验包层模块(TBM)的第一壁Be、Be球床中子增殖区、Li₄SiO₄陶瓷球床氚增殖区、以及结构材料的温度场和氦气流道内流场进行了三维数值模拟,研究了TBM的温度场及冷却管道内的氦气流场的分布。结果表明,除极小区域外,材料的温度在该材料所允许的工作范围之内;氦气表现出很好的流动和换热特性。

Abstract: Three dimensional temperature field and helium flow field of TBM are simulated using the general purpose computational fluid dynamics（CFD） code FLUENT.The temperature distribution of Be Armor,Be Pebble Bed,Li₄SiO₄ Pebble Bed,Structure Material of TBM,and helium flow field in the cooling pipe are presented.The research indicates that the work temperature of each material is under the material temperature allowed except some places where high temperature should be excluded in the design.The re-sults will provide references for further optimized thermal hydraulic design of ITER China TBM.
