Abstract

Describes the choice and implementation of some numerical algorithms for the simulation of fast transient, multicomponent, compressible inviscid flows interacting with deformable structures. In the analysis of problems of this kind, the equilibrium equations for the solid structure are usually formulated in a reference frame which moves simultaneously with the material (Lagrangian description). On the other hand, the computational fluid dynamics (CFD) analysis is normally formulated in a purely Eulerian manner, in which the discretization points are fixed in the reference frame. The study of fluid-structure interaction (FSI) phenomena thus requires the overall problem to be formulated in such a manner as to accommodate these two extreme situations. This generality is accomplished by the well-known Arbitrary Lagrangian-Eulerian (ALE) formulation.
