Abstract: The test results of some proper-designed vortex generators for eliminating flow separation in the corner region of a two-dimentional diffuser are presented. A divergent concave-shaped surface is chosen as the wall of the diffuser.The experimental results show that the pressure recovery is increased and the total pressure distortion and total pressure fluctuation at the exit of the diffuser are decreased for the proposed diffuser.The effects of the constructional parameters of the yortex generators on the performance are discussed.
