The fluid-structure interaction and the fluid flow are studied in cases of a fuel tank sloshing and overturning. A bi-phase liquid-gas material with an ALE formulation is used to define the interaction between water and air in the fuel tank.
In the case of sloshing, the fuel tank is subjected to a horizontal deceleration. The fuel tank container is modeled with a Lagrangian formulation and undergoes an elasto-plastic material law. Fluid structure coupling is taken into account.
The overturning of the fuel tank is studied by applying a variable deceleration. The tank container is not modeled as the boundary nodes are fixed. The Eulerian formulation is used.
