摘　　要：为研究小型反应堆上腔室的冷却剂混合特性,使用STAR-CCM+软件建立小型反应堆上腔室模型。利用组分输运模型,完成对上腔室混合特性的计算。研究发现,反应堆腔室的混合能力十分有限,不同堆芯出口冷却剂向单一出口的流量份额随距出口距离增大而不断减小,不同位置的冷却剂的流动方式也存在差异。In order to study the coolant mixing characteristics of the upper chamber of small reactor,the upper chamber model of small reactor is established by using STAR-CCM+software.Using the component transport model,the mixing characteristics of the upper chamber are calculated.It is found that the mixing capacity of the reactor chamber is very limited,the flow share of coolant from different core outlets to a single outlet decreases with the increase of the distance from the outlet,and the flow modes of coolant at different locations are also different.
