Three-dimensional dam break flow simulation using OpenFOAM

Abstract:

A dam is an engineering structure constructed across a valley or natural depression to create a water storage reservoir. The fast-moving flood wave caused by a dam failure can result in the loss of human lives, great amount of property damage, and have a severe environmental impact. Therefore, significant efforts have been carried out over the last years to obtain satisfactory mathematical numerical solutions for this problem. Due to advances in computational power and the associated reduction in computational time, threedimensional (3D) numerical models based on Navier Stokes equations have become a feasible tool to analyse the flow pattern in those days. Analytical studies of the dam break for a horizontal channel were performed by Dressler [1]. Several numerical studies based on 2D approaches have been validated against experimental data sets as demonstrated in [2] and [3]. Two dimensional …
