摘　　要：通过计算流体力学(CFD)数值模拟方法,对氚增殖剂球床内部的氦气流动特性进行了初步研究。分析了球床流通长度和流通截面对提氚气体压降的影响,获得了不同入口流速下规则堆积球床和随机堆积球床的压降和阻力系数。Based on the computational fluid dynamics simulation, the flow characteristics of helium gas in the pebble bed were preliminary investigated. The effect of the channel length of pebble bed and the channel cross section of the pebble bed on the pressure drop of purge gas was analyzed in detail. In addition,the pressure drop and Loss Coefficient of pebble beds with different packing structure at different flow rates were obtained.
