dcterms: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. Rotor-stator interaction is a source of high-frequency pulsations.

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.
