Local blast wave interaction with tire structure

Study of Blast Wave – Structure Interaction Using Exploding Wires Technique

Over the last decades there has been an ever increasing effort to better predict the load developed on a structure in explosion events. During the passing time, the computational abilities dramatically improved and the ability to predict quantitative results for complex scenarios became achievable. However, the need to validate the obtained numerical results became a necessity. The validation c...

Fluid Structure Interactions for Blast Wave Mitigation

Short-crested wave interaction with a concentric porous cylindrical structure

6 In this paper, theoretical study is carried out to investigate the general 3D short-crested 7 wave interaction with a concentric two-cylinder system. The interior cylinder is imperme8 able and the exterior cylinder is thin in thickness and porous to protect the interior cylinder. 9 Both cylinders are surface-piercing and bottom mounted. Analytical solution is derived 10 based on the linear po...

BEM-FEM coupling for wave-structure interaction

We present a numerical method, based on a coupling of finite elements and boundary elements, to solve a fluid–solid interaction problem posed in the plane. The boundary unknowns involved in our formulation are approximated by a spectral method. We provide error estimates for the Galerkin method and present numerical results that illustrate the accuracy of our scheme.

Blast-wave Snapshots from Rhic

I present fits with the so-called blast-wave model to single-particle spectra and HBT correlations from Au+Au collisions at a CMS energy of 130 AGeV. There is only little choice of freeze-out temperature and transverse flow velocity for which the model fits both the identified spectra and the correlation radii just well enough not to be excluded. The observed steep M⊥ dependence of Rside leads ...
