A numerical tool to compute hybrid Euler-Lagrange compressible models
Résumé
We present in this paper a numerical tool which provides approximations of solutions of hybrid Euler-Lagrange models. The basic underlying ideas of the whole scheme are presented, which rely on the use of relaxation techniques and on a previous investigation of second-moment realisable closures. Numerical tests involving shock and rarefaction waves confirm the suitability of the present approach. The impact of the turbulent noise and the influence of the mesh size are examined.
