Upwind adaptive finite element investigations of the two‐dimensional reactive interaction of supersonic gaseous jets

Abstract

SUMMARYWe describe an upwind finite element method aimed at numerically simulating the two-dimensional transonic flow of a reactive gaseous mixture. The method uses in particular a triangular finite element mesh, with an adaptive procedure based on mesh refinement by triangle division, and a n upwind non-oscillatory scheme based on a n approximate Riemann solver for the evaluation of the convective terms for all species. Results concerning the reactive interaction of two supersonic gaseous jets are presented.
