Abstract: The deceleration rate θ1 /λ, which is defined as the ratio of the momentum thickness to the distance where the free-stream velocity is reduced by 10 percent, is shown as an important and ...

Abstract: From a consideration of flow stability, it is shown that the onset of separation in a diffuser depends upon the local blockage factor. Using performance data for two-dimensional diffusers from ...

Abstract: Vortex generators, which consist of small blades, are applied to conical diffusers the divergence angles of which are 8, 12, 16, 20, and 30 deg, respectively. The area ratio of each diffuser ...

Abstract: A new combined five-hole probe with hemispherical head of 2.0 mm diameter is developed for the measurement of nonsteady three-dimensional water flow. Each pressure hole is connected to a small ...

Abstract: In order to visualize the three-dimensional flow in the impeller and the vaneless diffuser of a centrifugal compressor, water is used as the working fluid and streak lines of colored water ...

Abstract: Using three conical wall annular diffusers, geometries of struts mounted at the inlet tube were studied which were suitable for both the swirling inlet flow and the nonswirling inlet flow. ...
