CFD can be used to model flows in a sloshing fuel tank. Liquids inside the fuel tank are prone to sloshing due to a range of internal and gravitational forces that the fluid may experience during acceleration and vehicle or aircraft movement. CFD allows designers to estimate the range of forces on the walls of the container of the fuel tank for all the possible operational conditions that the vehicle or aircraft may experience. With its powerful abilities to model time-dependent free-surface flows, FLUENT validates its use as a strong CFD tool to model such complex transient flows.
