摘　　要：利用计算流体力学软件对安全壳废水排放系统管道及蝶阀的固体杂质颗粒冲蚀问题进行了模拟分析,跟踪了粒子的运动轨迹,计算得到了在不同流速下固体颗粒对管道及阀门的冲蚀情况,确定了受侵蚀严重的部位。Use of CFD softw are,the erosion of the solid particles in a round tube has been simulated,w hich has a butterfly valve and serves as a part of the liquid w aste discharge system of a certain equipment. The movement of the particles have been tracked,and the erosion quantity of the tube and the valve under different flow velocity have been calculated. Then,the position in w hich the erosion quantity is relatively high has been confirmed. The analysis result show s that the flow velocity is one of the most important factors w hich lead to erosion.
