DOI: 10.1016/j.ast.2021.107032
Abstract: Abstract The strong adverse pressure gradient and shock wave/boundary layer interaction that occurs in supersonic compressor cascade corner regions usually leads to large three-dimensional corner separations with extensive total pressure losses. This substantially restricts compressor… read more here.

DOI: 10.2514/1.j058488
Abstract: The proposed passive control method, blade-end slots, is implemented to reorganize the blade-end flow in a highly loaded compressor cascade under a wide incidence range at Ma=0.59. Both experimenta... read more here.
