摘要：
An impeller (2) with splitter blades (5) has a wide operating range without affecting the performance of the turbomachinery. The impeller (2) for a turbomachinery comprises a plurality of splitter blades (5) disposed between the full blades (4) adjacent to each other. Each of the splitter blades (5) is shaped in such a way that a spanwise distribution of a pitchwise position of a leading edge of the splitter blade is determined according to a spanwise and pitchwise non-uniformity distribution of fluid velocity of a fluid flowing into the splitter blade (5).
