Sharif University of Technology Scientia Iranica 1026-3098 12 2 2005 04 01 Inviscid Compressible Flow Computations on 3D Unstructured Grids 2484 EN M.T. Manzari Department of Mechanical Engineering,Sharif University of Technology Journal Article 2006 04 17 In this paper, an explicit finite element based numerical procedure is presented for simulating three-dimensional inviscid compressible flow problems. The implementation of the first-order upwind method and a higher-order artificial dissipation technique on unstructured grids, using tetrahedral elements, is described. Both schemes use a multi-stage Runge-Kutta time-stepping method for time integration. The use of an edge-based data structure in the finite element formulation and its computational merits are also elaborated. Furthermore, the performance of the two schemes in solving a benchmark problem involving transonic flow about an ONERA M6 wing is compared and detailed solutions are presented. https://scientiairanica.sharif.edu/article_2484_c7970f8bca99e1aed45c7e9353a5797d.pdf
