The paper describes a direct numerical resolution for turbulent counterflow flames. Following \textit{T. J. Poinsot} and \textit{S. K. Lele} [J. Comput. Phys. 101, No. 1, 104--129 (1992; Zbl 0766.76084)], the authors write the corresponding Navier-Stokes system and using the characteristic wave description they obtain the so-called Navier-Stokes characteristic boundary conditions NSCBC. Considering here the multidirectionality of the flame boundaries, the authors improve the previously known NSCBC within this context. They consider a first numerical scheme in the case of a laminar counterflow flame. They then apply the modified NSCBC in the context of laminar and turbulent counterflow flames.
