Les M\'Ethodes De R\'Esolution De Type " Lattice Boltzmann " Sont-Elles Utilisables Pour Simuler Les Jets Plasmas Souffl\'Es Atmosph\'Eriques Utilis\'Es En Projection ?

Abstract

In this study a new numerical approach of the fluid dynamic, the lattice Boltzmann method (LBM), is used to solved the stream in a atmospheric Argon-nitrogen plasma jet. The axial symmetry and the variation of density, viscosity and conductivity with the temperature are taken into account. The reliability of the results are evaluated from the shareware GENMIX and Jets & Poudres.
