摘要
本文使用Ｓ＿１／Ｓ＿２全三元送代计算和三元Ｎ－Ｓ方程解两种方法对含有分流叶片的Ｅｃｋａｒｄ离心叶轮内部三元流场进行了数值分析，并与激光测量值进行了比较。侧重分析了叶轮内部分离流动和射流尾迹区的形成和特点。
The flow filed in a centrifugal impeller with splitter blades has been analysed by the use of full 3D S2/S1 iterative solution and a 3D N-S code. Fairly good agrement was achived when the predicted results were compared with the L2F measurements. The numerical simulation demonstrate the details of the flow separation, the wake formation and the secondary flows development.
