SILVA, Luis Fernando Figueira da; AZEVEDO, João Luiz F.  and  KORZENOWSK, Heidi. On the development of an unstructured grid solver for inert and reactive high speed flow simulations. J. Braz. Soc. Mech. Sci. [online]. 1999, vol.21, n.4, pp. 564-579. ISSN 0100-7386.  http://dx.doi.org/10.1590/S0100-73861999000400001.

An unstructured grid Euler solver for reactive compressible flow applications is presented. The method is implemented in a cell centered, finite volume context for unstructured triangular grids. Three different schemes for spatial discretization are implemented and analyzed. Time march is implemented in a time-split fashion with independent integrators for the flow and chemistry equations. The capability implemented is tested for inert flows in a hypersonic inlet and for inert and reactive supersonic flows over a 2-D wedge. The results of the different schemes are compared with each other and with independent calculations using a structured grid code. The strengths and the possible weaknesses of the proposed methods are discussed.
