Impact of the Series of Obstacles During the Partial Destruction of the Tank

In this work, we studied the effect of a series of obstacles during partial dam failure, using the VOF method with a turbulent LES model. In the first part, we compared our numerical results to the experimental ones taken from the literature. Very good agreements are obtained for the 2D and 3D configurations, particularly the evolution of the flow velocity distribution and the change of water interface. In the second part, our model, developed in 3D, simulated the evolution of the behavior of the complex flow during a partial rupture, under the effect of series of obstacles. These obstacles act as a brake and reflect the driving forces of water and the forces of gravity. Resulting from the inversion of the water column, a stable and shallow regime slowly sets in.
