Keywords: fluid-structure interaction, finite volume, dynamic mesh, crosswind.
This paper deals with a general procedure to analyse fluid-structure interactions. To do so, we use the finite volume method which allows us to discretise the continuous operators modelling the fluid flow on one hand, and the solid behaviour on the other hand. The coupling is achieved by the pressure and shear stress applied from the fluid to the solid boundary and by the computational domain distortion induced by the solid deformation. The solution of the problem is achieved using numerical algorithms. Finally, we present some results on the application of the developed methodology on a test-case: a two-dimensional train cross-section under crosswind.
