| Abstract: | The cascade exiting flow field investigation was carried out in a low speed wind tunnel with four annular compressor cascades composed of conventional straight blades, positive leaned blades, positive curved blades and s type blades at near zero incidence respectively. It was studied that the different blades affected the exit energy loss distributions and the secondary flow velocity vectors . |
