Description
Summary:Sloshing makes it challenging to transport liquid-containing systems fast. Accurate prediction and effective suppression of sloshing are essential in many industrial applications. Two different methods are commonly used to numerically investigate the sloshing phenomenon: CFD simulation and equivalent mechanical model. Due to each method’s pros and cons, the solutions based on potential flow theory can be a good alternative for sloshing study. However, previous studies mostly focused on sloshing under sinusoidal oscillations, and only a little effort has been made to understand and suppress the sloshing under point-to-point movements. In this study, potential solutions for sloshing in a rectangular tank under horizontal point-to-point movements are newly derived and verified by comparing with the present CFD results. So far, the velocity profile of liquid-containing tanks has attracted little attention from the sloshing suppression point of view. However, simply a suitable choice of velocity profile (acceleration/deceleration duration) can lead to much-reduced sloshing. Results show that the present potential solutions are beneficial for designing the tank velocity profile for minimum residual sloshing under a given condition. It is also shown that the acceleration/deceleration duration affects the sloshing amplitude more significantly than its magnitude.
