其他摘要：This work presents the numerical and experimental analyses of the collapse of a water column over an obstacle. The physical model consists of a water column initially confined by a closed gate inside a glass box. An obstacle is positioned between the gate and the right wall of the box (inside the initially unfilled zone). Once the gate is opened, the liquid spreads in the container and moves over the obstacle. Measurements of the liquid height along the walls and a middle control section are obtained from videos. The simulations are performed using a moving interface technique, namely the Edge-Tracked Interface Locator Technique (ETILT) to describe the interface motion, and some physical aspects are considered via the model reported in Cruchaga et al., Comp. Mech., 39:453-476 (2007). The analysis involves column aspect ratio of 2 with different obstacle geometries. The numerical predictions agree reasonably well with the experimental trends.
