The lattice Boltzmann method has been widely used in computational fluid dynamics of low-Mach flows, and has proven to be CPU efficient and complex geometry friendly. Recently, its range of application has been extended to fully compressible reactive flows [1], with successful demonstrations in increasingly complex configurations, from instabil- ity problems [2], turbulent flames [3], fire-induced flows [4] to complex burners [5] and detonations [6]. This presentation will provide a brief overview of the recent progresses of Lattice-Boltzmann methods for reactive flows simulations.
