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.
