Study on the Influence of Radial Inlet Chamber Splitter Blades on the Oblique Flow Compressor Performance

The oblique flow compressor is one of the important components in compressed air energy storage (CAES) system. structural shape radial inlet chamber (RIC) directly affects performance, and a reasonable RIC design should achieve smallest total pressure loss outlet distortion as much possible to meet design. To study influence splitter blades, 4 RICs equipped with different numbers blades are designed, performance overall calculated. results show that increase number stall margin increases from 6.3% 13.94%. At point, isentropic efficiency highest for 17 ratio 11 blades. Compared direct axial intake mode, uniformity relative leakage distribution attack angle impeller leading edge under modes poor. However, an tip gradually increase. will simultaneously, though aerodynamic parameters improves, on downstream component weakens. There optimal RIC, which balances coefficient.
