Sloshing force in a rectangular tank with porous media

Abstract

The porous media in a water tank will affect the dynamic characteristics of the sloshing behavior significantly. The sloshing force is one of the most important features, especially when resonance occurs. In this paper, the analytical equivalent mechanical model and numerical regularized boundary integral method (RBIM) are presented and verified by a resonant test. The experimental measurements show the analytical solution is useful for the linear-flow regime, while the numerical method provides accurate prediction for the nonlinear-flow case. The quadratic equation for the pressure drop due to porous media can be available as the suitable parameters are determined.
