A Study on Dampening Effect of Fuel Sloshing in a Fuel Tank using Baffles

This paper represent the phenomenon of liquid fuel sloshing effectiveness on the different designs of baffles use when subjected to sudden uniform acceleration or stopping of vehicle. The objective this work is to study the occurrence of sloshing with the influence of different dimensional baffle are design like floating baffle circular baffle in alternating arrangement. The simulation of liquid free surface behavior under uniform acceleration is done using ANSYS-FLUENT software. A numerical model is developed based on Volume of Fluid (VOF) technique to track the free surface motion of liquid. This shows baffles with more improved designs reduces the longitudinal force an analytical model is formulated to find position of the free surface of liquid in a cylindrical and rectangular tank subjected to uniform acceleration. The free surface profiles obtained from the simulations are compared with the experimental results.
