NUMERICAL SIMULATION OF 3D DAM BREAK BY VOF METHOD
Abstract
Dams are one of the important installations for collecting and storing water, generating electricity, and protecting against floods and irrigation. This article presents the numerical results of three-dimensional modeling of a dam break. The proposed numerical model was verified by comparing numerical results with experimental measurements and numerical results of other authors. The numerical method is based on the Navier-Stokes equations describing the flow of an incompressible viscous fluid. The movement of the surface of the water is captured using the volume of fluid method (VOF), which leads to strict conservation of mass. The accuracy and reliability of the 3D model was tested using a small laboratory experiment on the destruction of the dam. The proposed model predicts well the impact pressure of the breakthrough flow. It was also determined in which part of the obstacle the maximum pressure occurs after the dam breaks. In threedimensional modeling of a dam break, various forms of obstacles were considered, with the help of which it will be possible to reduce the impact pressure. From the presented numerical results, the optimal form of the obstacle was determined, which can be used as an additional safety dam for the main dam.
