摘要:

基于计算流体力学(CFD)方法,结合国际热核实验反应堆(ITER)中实际使用的设计参数,对硅酸锂球床的传热特性进行了流固耦合传热分析,给出了多种工况下的热工水力结果。同时将用CFD得到的球床区域等效导热系数与相关实验的结果进行了比较。

Abstract:

The computational fluid dynamics (CFD) simulation of fluid solid coupling heat transfer for the beat transfer properties of Li4Sio4 pebble bed has been performed by referring the actual design parameters in the International Thermonuclear Experimental Reactor (ITER). The thermal hydraulic results under different working conditions are given. Finally, the results of equivalent heat conductivity in pebble bed region obtained with CFD are compared with the related experimental results.

Key words: Li4SiO4 pebble bed, TBM, Equivalent heat conductivity, Fluid solid coupling
