Abstract:

The sloshing phenomenon is the participation of liquid in the partially filled vessels or tanks, which is a primary consideration for designing and constructing many structures in offshore, offshore, and space engineering. Employing porous baffles of varying porosities is an effective way to minimize or/and control wave elevations in the sloshing tank. In the present study, analytical investigations were carried out for the sloshing motion in the clean tank (tank without baffles) and the tank with baffles. The two porous baffles of three different porosities consider in the rectangular sloshing tank. The porous baffles place at equal intervals in the sloshing tank. The analytical simulations were carried out under a range of swaying motions. During simulation, the sway excitation frequencies cover the clean tank's first five resonant sloshing modes. The two porous baffles of lower porosity levels in the sloshing tank are beneficial in suppressing the wave elevations in the sloshing tank near the first resonant mode.
