    Pulsations induced by roto-stator interaction: CFD vs. transfer matrix method

  • Original language description

    Rotor-stator interaction is a source of high-frequency pulsations. Presented paper focuses on simulation of these pulsations in low specific speed pump with guide vanes. Two approaches are compared: 3D simulation in time domain and 1D simulation in frequency domain. Three-dimensional unsteady computations of turbulent flow were carried out using commercial CFD software. Resulting pressure pulsations spectra were compared to simulations obtained by one-dimensional transfer matrix method.

    Pulzace vyvolané interakcí rotor-stator: CFD vs. metoda přenosových matic

  • Czech description

    Interakce rotor-stator jsou zdrojem vysokefrekvenčních talkových pulzací. Článek se soustřeďuje na pulzace v pomaloběžném článkovém čerpadle s rozváděcími lopatkami. Jsou porovnány dva přístupy: 3D simulace v časové oblasti a 1D simulace ve frekvenční oblasti. 3D simulace turbulentního proudění jsou provedeny komerčním CFD sotwarem. Výsledky jsou porovnány s 1D simulací založenou na metodě přenosových matic.
