摘要
运用计算流体力学程序(CFX)对板型燃料元件表面结垢对堆芯最热通道流量分配的影响进行了数 值计算分析。计算结果表明,最热通道由于两边燃料板结垢,在通道间隙宽度降低10％的情况下,最热通道 的流量分配系数与未结垢时相比降低18.2％。
With CFX code, the effect of crud on flow-rate distribution of hot channel in plate-type core is analyzed. The research shows that the flow-rate distribution of hot channel is decreased by 18.2%, on account of the clearance decrease 10% due to crud on the surfaces of both hot channel fuel plates in plate-type fuel elements core.
