ANALYSIS OF FLUID SLOSHING USING CAE TECHNQIUES

Any motion of liquid surface is termed as a sloshing. It can be caused by any disturbance to partially filled liquid container. So to constitute a slosh dynamic of liquid, liquid must have free surface. The slosh dynamic of liquid alters the system dynamic or stability significantly when liquid is interacting with the container. The motion of liquid with a free surface is of great concern in many engineering disciplines such as propellant slosh in spacecraft, rockets (especially upper stages), cargo slosh in ship and trucks transporting liquid (for example oil and gasoline) etc. To reduce the sloshing in moving container baffle is used as suppressing device. The aim of the present simulation to study the fluid behavior and variation of forces inside the transportation tank caused by sloshing, when the tank is subjected to sudden breaking, with transverse and transverse baffle with hole. In the present study an Arbitory Lagrangian Eulerian (ALE) approach to investigate the fluid sloshing at various filling ratios. The model used in the simulation is carried out for different geometries with different filling conditions.
