Fluid-structural interaction with application to rocket engines

The objective of this work is to develop a finite element model for studyin g fluid-structure interaction. The geometrically non-linear structural beha viour is considered and based on large rotations and large displacements. A n arbitrary Lagrangian-Eulerian (ALE) formulation is used to represent the compressible inviscid flow with moving boundaries. The structural response is obtained using Newmark-type time integration and fluid response employs the Lax-Wendroff scheme. A number of numerical examples are presented to va lidate the structural model, moving mesh implantation of the ALE model and complete fluid-structure interaction.
