Abstract: Vortex formations in and around the intake pipe are common problems that lead to poor pump performance and frequent maintenance. This numerical study was performed using the code Star-CD, where the grids were generated and the calculations were run. Two turbulence models were tested: the K- ε turbulence model and the two-layer turbulence model. Particular emphasis was placed in determining the location of near-intake pipe vortices. The numerical predictions obtained in this study are in good agreement with previous experimental and numerical investigations.
