CFD Analysis of Sloshing within a Tank with Porous Baffles

V. Tejashwar Reddy

Abstract: In fluid dynamics, sloshing refers to the movement of liquid inside another object. The liquid must have a free surface to constitute a slosh dynamics problem. The sloshing effect on a linearly moving partially filled diesel tank is studied using computational fluid dynamics with volume of fluid along with k-epsilon turbulence model to determine the sloshing behavior in the tank. In this study sloshing behavior of diesel fluid inside the tank is significantly reduced by using porous baffles. In this study, porous bed type porous model in fluent setup is used for defining porous nature of baffles. Two vertical transverse porous baffles are used in this study. Comparison of pressure acting on the front wall of the tanker for both the models i. e. one without any baffles and one with two transverse porous baffles is done in this study. The pressure vs. time plots of both the cases are plotted using x-y plots.
