Numerical Simulation of Two-Dimensional Dam Failure and Free-Side Deformation Flow Studies

A dam breaking is a major flood catastrophe. The shape, depth, and wave Doppler effect of initial water flow are all modified as result the interaction body with downstream structures after breach, forming diffraction reflection field. This study investigates problem single liquid, by creating two-dimensional simplified numerical model using VOF approach, analysing between barriers various forms failure flow, explains complex mechanism involving significant deformation free surface medium. According to findings, obstacles varying could obstruct break’s degrees, viscous dissipation characteristic at edge obstacle closely related slope site. simulation presented in this validated, demonstrating its accuracy for both gate-pulling wet-bed scenarios.
