摘　　要：为研究小型船用反应堆堆芯入口处冷却剂受横摇与纵摇的影响,利用CFD软件STAR-CCM+建立反应堆全堆模型并引入摇摆扰动,分析横摇与纵摇对反应堆堆芯入口处冷却剂流量变化与流量分布的影响。结果表明,横摇与纵摇对冷却剂流量变化影响基本相似而堆芯入口处整体流量分布受纵摇影响更大。In order to study the influence of roll and pitch on the coolant at the core inlet of small marine reactor,the whole reactor model is established by using CFD software STA.R-CCM+;and the roll disturbance is intreduced to analyze the influence of roll and pitch on the coolant flow change and flow distribution at the core inlet of react or The results show that the effects of roll and pitch on coolant flow are basically similar,while the overall flow distribution at the core inlet is more affected by pitch.
