Numerical simulation of hydrogen sloshing in tanks

Goals

Numerically simulate, in 3D, the sloshing of hydrogen in a tank depending on the filling level in order to predict the real loads applied to the structure, in the event of vehicle maneuvering or even an "air pocket" in aviation.

Innovations

Conventional techniques have difficulty simulating free surface flows as is the case here. The innovation is to develop the PFEM (Particle Finite Element Method) method which allows the fluid to be followed in a Lagrangian manner which facilitates the simulation of the free surface and its evolution. The fluid-structure interactions between the fluid and the reservoir will also be treated.
