Liquid sloshing is the relatively low frequency oscillation of the free surface of a partially full container. Intentionally induced sloshing in a container may be used as a means to limit excessive oscillations of light resonant structures, such as tall buildings and long-span suspension bridges.These devices are commonly called sloshing absorbers. The objective of this investigation is to demonstrate the effect of different flow obstructions, to increase the rate of energy dissipation in a trapezoid shaped sloshing absorber. Numerical investigations involve using Smoothed Particle Hydrodynamics (SPH) method. In addition, experimental observations are included to support the validity of numerical predictions.
