International audienceBecause of the lack of fluid-structure interaction FSI test cases, particularly for transient compressible flows, the present paper deals with a numerical and experimental study of the behaviour of a cantilever panel submitted to a shock tube flow. Our purpose is to confront our numerical model to an unsteady FSI problem. This study hopes to initiate a reference data bank in this domain. After a description of FSI numerical model, experimental device and diagnostic, a comparison is presented through the fluid flow structure and the panel deformations. A good agreement between numerical results and the experiments is obtained

International audienceThis paper deals with the numerical study of the interaction of a shock wave and a bubble. The three different density ratio cases between air and bubble are investigated: light/heavy, heavy/light and close density. The numerical simulations are compared to the experiments of Layes et al. Phys. Rev. Lett. 91, 17 2003. These three cases may allow us to better understand the vortex deposition by the baroclinic terms. Moreover, the behavior differences between the deformation of a bubble and a cylinder collided by a shock wave are shown. An analytical approach to evaluate the final volume of an inhomogeneity submitted to a shock wave interaction is also presented and discussed
