EFFECTS OF THE TIP-CLEARANCE TO THE STALL PROCESS AND CIRCUMFERENTIAL GROOVE CASING TREATMENT IN A TRANSONIC AXIAL COMPRESSOR

摘要：

With a validated in-house developed highly accurate and efficient code, the present paper studies the performance of a transonic compressor, NASA Rotor 37, with circumferential groove casing treatment (CGCT). The simulation shows that without casing treatment, with different tip gap, the stall processes exhibit different mechanisms. These differences also strongly affect the effectiveness of the CGCT.
