Abstract: The objective of this investigation is to characterize a quasi-standing-wave pattern having a wavelength two orders of magnitude smaller than the corresponding acoustic wavelength, and relate it ...

Abstract: In studies of a diffuser operating with inlet flow oscillations, it has been found that large amplification of the inlet velocity oscillations occurs within the diffuser when the throat Reynolds ...

Abstract: Turbulent boundary layers experiencing a time mean adverse pressure gradient and a controllable periodic oscillation are examined experimentally over a tenfold range of dimensionless frequencies, ...

Abstract: This paper describes experimental research aimed at improving our understanding of the complex unsteady three-dimensional flow field associated with the interaction between a pump impeller and its ...

Abstract: This paper describes an investigation into the use of CFD for highly loaded pump diffuser flows. A reliable commercial Navier-Stokes code with the standard k-ε turbulence model was used for ...
