Research on the Suppression Effect Law of Different Baffle Positions on Liquid Sloshing in Spherical Tank

This study aims at investigating the effect of baffle position on the liquid sloshing in a laterally moving spherical tank. To simulate weakly compressible viscous flow in the tank partially filled with liquid, the SPH method has been utilized. The numerical solutions of Navier-Stokes equations are deduced, along with the artificial viscosity and pressure term, dynamic boundary treatment has been implemented to deal with the boundary problem. Four probes are located at different positions inside the tank's wall to monitor the pressure exerted on it. Four tank models with different baffle positions (different h(p)) are built to examine how it will suppress the sloshing phenomenon. Simulation results show that: The pressure acting on the tank wall is larger when the position is closer to the tank's bottom. Among the four tank models, the suppression effect on liquid sloshing is the best when baffle position h(p)=0.5.
