Comparison of numerical flow models based on a dam failure example

Siniša Družeta, Lado Kranjčević, Jerko Škifić

Abstract

The numerical 2D shallow water model developed using the Stripp 12 software, and the 3D Navier- Stokes two-phase free-surface flow model based on the Fluent software, are compared and evaluated. The standard laboratory dam collapse experiment, defined in the scope of the international CADAM project, was used as a test example. The analysis of results shows that highly accurate failure results have been obtained for both models, although the 3D free surface flow model has proven to be more accurate
