Abstract
The paper present the different performances of four different hub curve shape in transonic compressor rotors by CFD method. The results show that different hub design have obvious influences both on the performances and the flow fields. Comparing with the linear hub design, concave hub design improves the flow capacity near the rotor's hub, so increase the work capacity of blade hub fields. And also the concave hub design decrease the hub blockage and loss coming of hub corner separation. Convex hub design deteriorate the hub fields and performance. The S-shape hub design is a balanced design for efficiency and wok. The main effect of hub shape design action on shock-wave locations and racial flows.
