Numeryczne modelowanie rozmyć poniżej budowli piętrzących

The scour below the dam is numerically simulated using an Eulerian two-phase model that implements Euler-Euler coupled governing equation for fl uid and solid phase and a modifi ed k-ε turbulence closure for the fl uid phase and comparison with laboratory results. The modeling system being a part of CFD software package FLUENT. Both fl ow-particle and particle-particle interactions are considered in the model. During the simulations, the interface between sand and water is specifi ed using a threshold volume fraction of sand. The predictions of bedform evolution are in good agreement with conducted laboratory measurements.
