Experimental Investigation into the Effects of Riblets on Compressor Cascade Performance.

The effects of adding riblets to the blades of a subsonic, linear compressor cascade were investigated at the Air Force Institute of Technology. Three blade configurations were tested, including a set of unmodified NACA 64- A905 series blades, a set with riblets applied to the suction surface, and a...

The effects of adding riblets to the blades of a subsonic, linear compressor cascade were investigated at the Air Force Institute of Technology. Three blade configurations were tested, including a set of unmodified NACA 64- A905 series blades, a set with riblets applied to the suction surface, and a set with riblets on the pressure surface. Performance was evaluated over a wide range of Reynolds numbers, and at low and high free stream turbulence levels. Cascade performance was evaluated in terms of total pressure loss coefficient, turning angle, and static pressure rise. No riblet configuration offered robust cascade performance improvements; however, performance was significantly enhanced under certain specific conditions. Riblets also degraded cascade performance at other conditions. 2012-08-22T15:33:41Z 2012-08-22T15:33:41Z 2002-12 http://hdl.handle.net/10945/10804 This publication is a work of the U.S. Government as defined in Title 17, United States Code, Section 101.
