Abstract:Through experimental investigation and topological analysis, the vortices in compressor cascade with endwall fences are analyzed. It is indicated that there are a pair of vortices near the suction surface fence through the test result of cascade flow fields and flow visualization. The passage vortex is weakened. The position where the suction sides of the horseshoe vortex intersect the suction surface of blade is removed to downstream, the range which is effaced by the suction side of the horseshoe vortex along the height of blade is shortened, so the flow in the suction surface corner region is improved and the compressor cascade loss is reduced.
