... to a higher-pressure condition at the blade exit. The ‘separation bubble’ thus formed could, in many cases, trigger flow transition from laminar to turbulent conditions on reattachment further downstream of the point of separation. Since blade profile losses depend on the transition location, the modification...

... a /C = 0.065·10 −5 , 4.417·10 −5 and 7.428·10 −5 have been measured at a fixed Reynolds number of 5.2·10 5 and freestream turbulence intensity of 0.2%. For the reference Smooth surface of R a /C = 0.065·10 −5 , a laminar separation bubble forms from about 64% to 83% of the chord length. Displacement...

... of the pressure side and reaches the suction side of the adjacent blade. Strong interaction between the suction side boundary layer and incident shock wave exists in this region, and the separation bubble appears in the no jet case. The complex shock wave system and corresponding flow characters are analyzed...
