Numerical Simulation of Effects of Two Different Baffles on Liquid Sloshing by MPS Method.

In this paper, a series of numerical models has been developed lo study the effects of two different baffles on liquid sloshing under the six degree-of-freedom (6-DOF) excitation. The moving particle semi-implicit (MPS) method is a mesh-free method which can simulate flow with large deformation and nonlinear fragmentation of free surface effectively. The MLParticlc-SJTU solver based on improved MPS method is first validated against the available experimental data for 3-D liquid sloshing in a rectangular tank under horizontal excitation. Then, the study of liquid sloshing in another tank is carried out under the 6-DOF excitation. The detailed (low field and the variation of impact pressure can be observed clearly. In addition, the effects of two different baffle types on liquid sloshing, two vertical baffle and two ring baffles, arc further analyzed based on previous rectangular tank. Results show that the sloshing and pressure amplitudes arc obviously reduced due to these baffles and the ring baffles arc more effective on restraining sloshing. [ABSTRACT FROM AUTHOR]
