摘　　要：采用建立在拟流体假设基础上的离散介质动力理论对不同弯管及复杂管线内的气固多相流动进行了计算 ,得到了各流动参数的分布情况 ,分析了弯曲角度和相对曲率半径对不同尺寸粒子的分离效果 。Gas solid multi phase flows in curved pipes with different angles and curvatures are simulated upon the kinetic theory of granular medium, which is based on the Euler model. Flowing parameters of the multi phase flow are obtained. The effect of the angles and curvatures of the curved pipes on the particle separation is analyzed. Numerical simulation adopting CFD software provides an effective method to study multi phase flow characteristics of primary air in combustion system of power plant boilers.
