CFD Analysis of Fuel Tank to Reduce Liquid Sloshing

This paper demonstrates the sloshing phenomena of a cylindrical tank with and without baffles. The main objective of this study is to design baffles of different configurations to reduce sloshing in a cylindrical tank partially filled with gasoil-liquid subjected to only longitudinal acceleration and deceleration. Two different baffle designs have been introduced in the present study. A 3-D transient analysis of a cylindrical tank was carried out using ANSYS-FLUENT with and without baffles. Volume of Fluid (VOF) method was used to study the free surface profile of the fluid in the considered tank. Pressure distribution, velocity distribution and force distribution have been studied in the present study. It has been observed that the new design of baffle was able to reduce sloshing effectively.
