A particle-based simulation of a dam break interacting with an obstacle

Description
Knowledge of dam break events is crucial to assess the potential hazards of sudden water releases and develop better disaster management plans. This work develops a computational model based on a messfree method, called the Smoothed Particle Hydrodynamics (SPH), to simulate situations when a dam breaks and there is an obstruction in the route of the flowing water. The model accurately simulates the complex interactions between fluid and structure by including a weakly compressible fluid and using a cubic kernel function to govern particle interactions. To maintain realistic simulation results, a repulsive boundary condition is used to prevent particles from passing through solid boundaries. The simulations aim to investigate the impact of the obstacle on flow behavior, and the outcomes are checked against the experimental data. These results show that the SPH framework accurately simulates dam break dynamics with an obstacle, aiding risk assessment and disaster response planning.
