Abstract
This paper highlight the influence of three numerical turbulence models on the convergence and the
performance of flow simulation. The computational comparative study was realized using the COMSOL
Multiphysics 5.5 code. Turbulence was generated numerically in a centrifugal water pump using the k−ϵ, k−ω
and k−ω SST models. However, the geometry was performed on SolidWorks due to its complexity. The flow
modelling was mainly based on the resolution of the stationary Navier—Stokes equations. The effects of the
tested models on CFD numerical simulation were examined. It was found that the best calculation precision was
obtained using the K−ω model, while the lowest was provided by the K−ω SST model. However, a very low
calculation cost was obtained by the latter. As well as better pumping performance were recorded.
