... in a centrifugal pump. The resulting fluctuating loads are quantified using numerical computations. For the chosen configuration transient PIV data are available for validation. In addition to measuring the stall frequency in the stationary frame, the CFD data is analyzed in the rotating frame. A Fourier analysis...

... above 2. The results show that the lift is driven to a large extent by the acceleration of the oscillation rather than its velocity. This should be considered when modeling the fluid-structure coupling in reduced-order VIV models. drag flow simulation fluid oscillations Fourier analysis numerical...

... on the blades. The application of the above technique to the analysis of cavitation in a test inducer lead to the detection of the rotating stall instability observed under the same operating conditions by means of Fourier analysis of the inlet pressure signals. The results confirm the potential...
