Abstract

This paper considered the problem of numerical simulation of an incompressible dam break flow consisting of three phases. The movement of the water free surface was carried out using the Newtonian fluid model, and the mud impurity movement was performed by the non-Newtonian fluid model based on the VOF method. The PISO numerical algorithm was chosen as a numerical method for solving equations. This paper discusses the problems of dynamic loads arising from the impact of a dam break flow using numerical modeling. The obtained numerical results were compared with the two experiment results, which allow confirming the behavior of the instantaneous flow and the evolution of pressure at the relative points of the obstacle. Moreover the water flow and non-Newtonian fluid for different forms of obstacles were also modeled. It was found that a non-Newtonian fluid extremely reduces the maximum shock pressure value of the water flow.
