INPUT SHAPING BASED CONTROL OF SLOSHING IN A RECTANGULAR TANK WITH HORIZONTAL BAFFLES

Suppression of liquid sloshing in moving tanks is essential in many engineering applications. The sloshing can be successfully suppressed by installing baffles inside the tank or applying a control theory called ‘input shaping’ to the tank velocity profile. This study aims to numerically investigate the combined effect of horizontal baffles and input shaping on sloshing in a horizontally moving tank. Numerical simulations are carried out for the two-phase flow of water and air using a volume-of-fluid(VOF) model. Results show that the damping effect of baffles strongly depends on the baffle height but input shaping provides additional control capability for all the baffle heights considered.
