Document Type and Number:
WIPO Patent Application WO/2023/035576
Kind Code:
A1
Abstract:
A plane cascade flow field quality improvement system combining suction and a flow guide tail plate. The plane cascade flow field quality improvement system comprises a fixed base (1) and a cascade test bench (2) provided on the fixed base (1). An air supply tube (3) is provided at one end of the cascade test bench (2), an air discharging port (4) is provided at the other end of the cascade test bench, and a cascade test member is provided in the middle of the cascade test bench (2); the left and right sides of the cascade test bench (2) are correspondingly provided with a left rotating disc (5) and a right rotating disc (9), the left rotating disc (5) and the right rotating disc (9) are rotatably mounted on the cascade test bench (2), and an air guide gap communicated with the air supply tube (3) exists between the left rotating disc (5) and the right rotating disc (9); one side of the cascade test member is provided on the left rotating disc (5), and the other side of the cascade test member is provided on the right rotating disc (9). In the system, the quality of the cascade flow field is improved in a manner of combining a suction mechanism and a flow guide mechanism, a good improvement effect is achieved, operation and adjustment are simple and convenient, and accurate adjustment and improvement of the quality of the cascade flow field can be achieved.
