A Lattice Boltzmann Relaxation Scheme for Compressible Flows

Jeudi 11 octobre 14:00-15:00 - S.V. Raghurama Rao - Department of Aerospace Engineering, Indian Institute of Science, Bangalore

Résumé : Traditional Lattice Boltzmann Method (LBM) is limited to incompressible flows, due to a built-in low Mach number expansion of the equilibrium distribution. A Lattice Boltzmann Relaxation Scheme for compressible flows is presented. The equilibrium distributions are simple functions of conserved variables and fluxes, avoiding low Mach number limitation. The results are presented for 1-D and 2-D Euler equations. New approaches are also introduced to approximate viscous Burgers equation.
