... of a novel fluid impeller-based ejector. The authors’ motivation towards this study was in understanding the boundary conditions leading to spatial deterioration of pseudoblades. Flow around stationary, axisymmetrically aligned rotors (the ramp vane and double cone type), held in a primary supersonic flow...

... vortex behavior of density changes around the wing was found to be relatively inconsequential even at the higher end of the Mach scale investigated. By a freestream Mach number of 0.4 and at low clearances, local supersonic flow regions were established close to the suction peak of the lower wing surface...

... for supersonic flow. Observing the contour plots in Fig. 9 , the main differences are concentrated in the subsonic region dominated by the wake (dotted line). For both transonic and supersonic cases, a low negative loss coefficient, which can be detected in the so-called free wake regions, indicates a positive...
