Numerical simulations of cavitating pump flow in consideration of centrifugal and Coriolis force are performed. For the simulations a homogeneous model for the liquid‐vapor two‐phase flow is used. The pump investigated is a radial type of low specific speed (n q = 18) with parallel shroud and hub. Numerical results such as detailed visualizations of the unsteady vapor distribution and time averaged pressure distribution in comparison with experiments are provided.
