In this work, the application of sedFoam, an Eulerian-Eulerian two-phase flow model, to scour process is presented. Two configurations are investigated : the two-dimensional scour under a submarine pipeline and the three dimensional scour around a vertical cylindrical pile. The results show that the two-phase flow model is able to reproduce qualitatively the scour mark development and allows to get more insight into the fine scale sediment transport mechanisms involved in the scour process. Beyond the applications presented here, this contribution is a proof of concept that two-phase flow numerical simulations are now possible for complex multi-dimensionnal flow configurations.
