Simulation of Fuel Sloshing – Comparative Study

M. Vesenjak, Prof. Z. Ren, Z. Zunic (Universität Maribor); A. Hummel (DaimlerChrysler AG) The paper outlines different approaches to fluid-structure interaction modelling in LS-DYNA. Different formulations (Lagrange, Euler, ALE and SPH) are evaluated and compared with experimental observations of a fluid sloshing problem in a simple container box. Computational simulations have shown that the motion of the fluid can be best described with the alternative methods in LS-DYNA. Additionally, such methods are very economical and suitable for analyses of large and more complex models.
