This paper presents a computational method for blade-to-blade flow in centrifugal compressor's impeller with splitter blades. The method uses unitary control equation to handle the solutions in different ranges. The solutions are transimitted from one subrange to another automatically by program. Referring to existing method, the determination of split flow ratio is made by interpolation of coordinate of the leading adge of the splitter blades with considering the influence of outlet conditions.

This paper presents a computational method for blade-to-blade flow in centrifugal compressor's impeller with splitter blades. The method uses unitary control equation to handle the solutions in different ranges. The solutions are transimitted from one subrange to another automatically by program. Referring to existing method, the determination of split flow ratio is made by interpolation of coordinate of the leading adge of the splitter blades with considering the influence of outlet conditions. Upstream boundary conditions are determined by inlet axial velocity and the influence of blades on the upstream and downstream boundary conditions-by equal-circulation change in absolute velocity in outlet range. Numerical examples show that the length and periphery position of splitter blades have large influ-ence on flow field. When the leading adge of die splitter blades is located midway between the two long blades and splitter blades incline to pressure surface of long blades, the flow field is much improved and blade load becomes smaller and the outlet Kutta condition is satisfied.

本文提出了计算具有分流叶片的离心式压缩机叶轮跨叶片方向的计算方法,这一方法运用统一的控制方程处理不同区域的问题,在每一个区域之间的数据结构联结均有程序自动完成。分流比的确定参照现有的方法,以分流叶片前缘点坐标插值获得,并考虑出口条件的影响。根据叶轮进口轴向分速和叶片对上游的影响确定上游过界条件,下游边界条件根据绝对速度等环量变化确定。算例结果表明,分流叶片长度、圆周位置均对流场有很大影响,当分流叶片前缘处于相邻两长叶片中间,而后部偏向长叶片压力面一侧时,流动状况有较大改善,并且叶片载荷减小,出口库塔条件满足。

On the basis of thin-airfoil theory, in this paper the calculating method of unsteady fluctuating lift of an annular cascade under .periodic gusts has been given, and the effects of geometrical and aerodynamic parameters of the centrifugal compressor on unsteady fluctuation lift analyzed. Using the random pulse modulation theory, a general model for calculating harmonic and broadband noise of the centrifugal compressor, and theoretical investigation of the acoustic radiation of vaned diffuser are presented. The method presented by this paper can be used to predict the acoustic radiation power of vaned diffuser due to interaction with impeller viscous wake. The results of the calculation are in good agreement with those measured by the experiments.
