Sloshing is a phenomenon which is seen widely occurring in liquid filled tanks which have large volume. Sloshing is the phenomenon which is the interaction of fluid and the structure of the tank. In this paper we are undertaking the task to reduce the sloshing effect in aircraft fuel tanks by introducing two different baffle designs. A baffle is a device which is used to restrict the flow of a fluid. In this research paper we are using the Boeing 747-200 which is one of the largest passengers carrying aircraft currently in operation. The designs were constructed on the Solidworks, and for simulating the effects of sloshing we are using Ansys simulation software. The computational Fluid Dynamics module is best to simulate conditions for the sloshing as various parameters can be controlled and dictated accordingly. The paper consists of results and comparisons between the current model in operation and the two designs of baffles used to reduce the effect of sloshing. The results are promising and saw that the designs are successful in achieving the objective of the paper. In oval shaped design of fuel tank and in partial horizontal and vertical combination design of fuel tank, we have managed to reduce the turbulence kinetic energy by 78.704% and 99.935% respectively. Further, attempts can be undertaken to improve the designs of the baffles used and achieve further reductions in sloshing.
