Abstract: Numerical simulation of dam-break water flow over a horizontal dry bottom was performed. Computational technologies including methods for determining the position of the interface and the continual model of the surface tension force implemented in PIFI code, and OpenFOAM software package with interFoam solver and various versions of the two-parameter ($k{-}\varepsilon$)-model with adjustments made taking into account the behavior of flows in areas with small Reynolds numbers were modified and verified. Calculated integral characteristics of dam-break flow were analyzed and compared with measured data. It is shown that taking into account the surface tension and using an adequate turbulence model leads to deceleration of water movement and hence to a decrease in the speed of the wave front, resulting in better agreement between the results of calculations and laboratory experiments.
Keywords: dam-break flow, water column, wave front, free surface, volume fraction, surface tension, turbulence models, computational fluid dynamics.
