Tsangaris, SDrikakis, DA ZONAL-LOCAL solution method is developed for the solution of the compressible Navier-Stokes equations. The main feature of the method is coupling of the Navier-Stokes equations with the Euler equations and the local mesh solution procedure. Mesh sequencing (multilevel) technique is also used for the improvement of the efficiency of the algorithm. The methodology is applied to turbulent flowfields past an airfoil. A flux vector splitting method with an upwind scheme up to fourth-order accuracy is used for the discretization of the inviscid fluxes. The system of the equations is solved by an unfactored implicit method using Gauss-Seidel relaxation.http://hdl.handle.net/123456789/111141760ISI:A1993MA623000050001-145210.2514/3.1184617593110engAMER INST AERONAUT ASTRONAUTAIAA journalComputational methodsTurbulent flowFluid dynamicsnavier-stokes equationAirfoilsVectorsImplicit methodsEuler equationsFlux vector splitting methodInterpolationRelaxation processesAlgorithmsGauss-Siedel relaxationIterative methodsNavier-Stokes equationsZonal local solution methodZonal-local solution method for the turbulent Navier-Stokes equationsjournalArticle1993Δημοσίευση σε περιοδικόPublication in journalΑεροδιαστημική μηχανικήAerospace Engineeringisi - Engineering, Aerospace includes resources concerned with astronautics, aeronautics, aerospace, and aviation.
