Erosion induced by solid particle impingement
is a very commonwear mechanism in turbomachinery and
Computational Fluid Dynamics is one of the most widely
used tools for its prediction. In this article, erosion is modeled
in one of the channels of a centrifugal pump using
OpenFOAM®,which is an Open Source CFD package. A review
of some of the most commonly used erosion models is
carried out in an Eulerian-Lagrangian frame along with a
comparative study of the erosion rates obtained with each
model. Results yielded some disparities between models
due to the different factors taken into consideration. The
mesh is then deformed to obtain the resulting eroded geometry.
