摘　　要：文章分析了流体在弯管内的流动特性 ,从理论上推导出流经弯管的流体流量与压差的关系的基本公式。利用PHOENICS软件对弯管内流体的流动速度、压力分布进行了计算 ,得出了流量与弯管内最大压差的关系与实验一致的结果 。Dynamic characteristics of the fluid passing through the elbow are analyzed. The basic formula of the relationship of the discharge and the pressure difference passing through the elbow theoretically deduce out. The distribution of the velocity and the pressure of the fluid passing through the elbow are calculated by the PHOENICS software. The results in accord to the test reveal that the relationship of the discharge and the pressure difference of the elbow. The relation between the discharge coefficient and the constructure parameters of the elbow are analyzed.
