3D Finite Volume simulation of acoustic waves in the earth atmosphere

Autor: H. Jourdren, P. Havé, S. Del Pino, Bruno Després, P.-F. Piserchia

Publikováno v: Computers & Fluids. 38:765-777

We present a very high-order Finite Volume discretization of the 3D linearized convective Euler equations for the simulation of acoustic waves in the Earth atmosphere. We also derive a weakly nonlinear model for the approximation of N-waves. We discu

Recent progress in high-gain direct-drive inertial confinement fusion with the laser Megajoule is reviewed. A new baseline direct-drive target design is presented which implodes with a two-cones irradiation pattern of indirect-drive beam configuratio

Stochastic design optimization: Application to reacting flows

Autor: C. Enaux, H. Jourdren, Didier Lucor, Pierre Sagaut

Publikováno v: Computer Methods in Applied Mechanics and Engineering. 196:5047-5062

One concern in the optimization of realistic complex systems is to ensure that the optimal model response is reliable and robust with respect to the inherent uncertainties associated with the design variables, constraints and the objective function.

Simulation of the Paraxial Laser Propagation Coupled with Hydrodynamics in 3D Geometry

Autor: F. Duboc, J. Metral, O. Morice, M. Casanova, Ph. Ballereau, D. Dureau, R. Sentis, H. Jourdren, P. Loiseau

Publikováno v: Journal of Scientific Computing. 33:1-24

We address here numerical simulation problems for modeling some phenomena arising in plasmas produced in experimental devices for Inertial Confinement Fusion. The model consists of a compressible fluid dynamics system coupled with a paraxial equation

Effects of microstructure on shock propagation in foams

Autor: B. Canaud, F. Garaude, H. Jourdren, X. Fortin, F. Philippe

Publikováno v: Laser and Particle Beams. 22:171-174

Foams are an important component of various inertial confinement fusion target schemes. The propagation of shock waves in foams is also an important issue for many other laser experiments (e.g., laboratory astrophysics experiments). The usual approac
