Abstract
Proper Orthogonal Decomposition (POD) is based on a space and time decomposition and on the finding of eigenfunctions. It is a technique for recognizing or identifying key dominant features in data sets. The release of high sand concentrated in water induces a flow with particular structures as showed experimentally by Villaret et al. [1]. Two-phase flow simulations with no current were presented by Guillou et al. [2]. The present paper shows the POD-analyses of results of such a simulation with and without current. Two spatio-temporal fields, the solid volume fraction and the solid phase velocity within the sediment release coherent structures are successfully captured by applying Proper Orthogonal Decomposition on numerical simulation results..
