Abstract
In this paper, we investigated the problem of dam breakage. The authors studied this problem using numerical modeling based on the Navier-Stokes equations with a turbulent k-epsilon RNG model and used the Volume of Fluid (VOF) method and the PISO algorithm. To verify the numerical model, the authors used the test problem of dam break in a 450 channel. The simulation results were compared with experimental data and with numerical data of another author. Having convinced of the correctness of the mathematical model, the authors carried out a numerical simulation of the main problem in three versions: without barriers, with one obstacle, with two obstacles. As the obstructions restrained the flow, a decrease in the water level and a slower time for the appearance of water could be observed. The main goal of this work is to analyze the flow in a channel with complex turn reliefs.
