Abstract :In the previous works, experiments were made with flat vanes in diffusers with divergence angles of 30°, 40°, and 60°, and showed the basic criteria for effective vane configurations with source-point translation. In the present work, tests were made with flat vanes in two-dimensional diffusers, to determine the relation between pressure recovery and flow regime. For the optimum vane configurations with source-point translation on the pressure recovery, the flow regime in the downstream duct is also greatly improved. The area of separation is considerably reduced, and the velocity profiles in the downstream duct can be flattened. However, the section where the velocity profile is to be uniform can be attained at the far distance in the downstream duct, compared with the pressure recovery section.
