Three-dimensional multiple-relaxation-time discrete Boltzmann model of compressible reactive flows with nonequilibrium effects
Based on the kinetic theory, a three-dimensional multiple-relaxation-time discrete Boltzmann
model (DBM) is proposed for nonequilibrium compressible reactive flows where both the
Prandtl number and specific heat ratio are freely adjustable. There are 30 kinetic moments of
the discrete distribution functions, and an efficient three-dimensional thirty-velocity model is
utilized. Through the Chapman–Enskog analysis, the reactive Navier–Stokes equations can
be recovered from the DBM. Unlike existing lattice Boltzmann models for reactive flows, the …
