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.
