Numerical investigation of the interactions between a low-hypersonic shock wave and a water droplet: VOF and DI methods comparison Open
In this paper, we present the hydrodynamic mechanisms which occur between a low-hypersonic shock wave and a millimetric water droplet.To do so, two numerical models, based respectively on the Volume of Fluid (VOF) and Diffuse Interfaces (D…

Experimental and numerical study of thin fragments protection for radiographic detectors Open
To perform a non-intrusive measurement on a pyrotechnic setup, we usually use radiography. But, the X-ray generator and the detectors of the radiographic chain must be protected against the blast and. We carried out an experimental campaig…

Hypervelocity impacts into porous graphite: experiments and simulations Open
We present experiments and numerical simulations of hypervelocity impacts of 0.5 mm steel spheres into graphite, for velocities ranging between 1100 and 4500 m s −1 . Experiments have evidenced that, after a particular striking velocity, d…

Enhancement of a dynamic porous model considering compression-release hysteresis behavior: application to graphite Open
Because of their shock wave attenuation properties, porous materials and foams are increasingly used for various applications such as graphite in the aerospace industry and polyurethane (PU) foams in biomedical engineering. For these two m…
