Abstract
The interactions between a deformable solid and surrounding fluid are non-linear multiphysics prob- lem that are crucial for the design of many engineering systems. The fictitious domain method is one of the numerical methods to solve FSI problems and has been successfully implemented for FSI problems involving incompressible flows. The objective of the present work is to adopt the fictitious domain method to study fluid-structure interaction problems involving compressible fluids. For this method we are employing Eulerian and Lagrangian finite element formulation for the fluid and solid, respectively, and both bodies are coupled using a Lagrange multiplier. This multiplier allows the solid not to be integral part of the fluid mesh, thus avoiding the need of mesh updating as in case of other numerical methods for FSI problems.
