Abstract

In the present paper, the computational fluid dynamics for one of the most challenging problems of two-phase flows; namely, the unsteady movements of dam break flow, is introduced. The governing momentum equations are solved numerically using the control volume approach over a regular two-dimensional computational grid. The level set method is applied for predicting the transient movements of the dam break free surface flow with a high accuracy solution procedure. The effects of the geometrical parameters of the initial dam shape and the fluid properties such as density, viscosity and surface tension on the dam front movement and dam topological changes are investigated. The obtained results showed a faster movement of the dam front in the downstream direction by increasing the dam height and the fluid density. However, by increasing the fluid viscosity, a slower motion of the dam front is obtained. Moreover, the variation of the fluid surface tension showed a slight effect on the movement of the dam front.
