Recent progress to model LH2 sloshing in flexible LH2 tanks by using a coupled CFD-CSM approach

Kurzfassung

In the presentation recent progress to simulate the loads in cryogenic LH2 tanks due to isotropic sloshing under severe acceleration pulses is presented. Considered load cases include aircraft emergency situations such as rejected take-off and survivable crash scenarios. The focus of the simulation studies is the evaluation of a 2-way coupled simulation approach with a meshless CFD solver for the fluid and a Finite Element based CSM solver with explicit time integration schema.
