Aiaa 98–0133 Compressible Navier-stokes Computations on Unstruc- Tured Quadrilateral Grids by a Staggered-grid Chebyshev Method
نویسنده
چکیده
We describe a new spectral multidomain method for the solution of the compressible Navier-Stokes equations. Within each subdomain, the method collocates the solution unknowns and the gradients at the nodes of the Gauss-Chebyshev quadrature. The total fluxes are evaluated at the nodes of the Gauss-Lobatto quadrature. Both conforming and non-conforming subdomain grids are allowed. Two examples are included to show the behavior of the method. First, exponential convergence is shown for the Couette flow on an unstructured grid quadrilateral grid. Next, subsonic flow over a backward facing step is solved on a non-conforming grid and a comparison to experiments is made.

Aiaa 98–0132 Euler Computations on Un- Structured Quadrilateral Grids by a Staggered-grid Chebyshev Method
A high order staggered-grid Chebyshev multidomain method is used to compute the Euler gas-dynamics equations on unstructured quadrilateral meshes. New results show that the method reduces to the first order upwind scheme when zeroth order polynomial approximations are used, and that by a simple reconstruction procedure the standard Chebyshev collocation method can be recovered. Local time-stepp...
متن کاملComputation of flows with shocks using the Spectral Difference method with artificial viscosity, I: Basic formulation and application
The present work combines the Spectral Difference method with an artificial viscosity based approach to enable high-order computation of compressible fluid flows with discontinuities. The study uses an artificial viscosity approach similar to the high-wavenumber biased artificial viscosity approach (Cook and Cabot, 2005, 2004; Kawai and Lele, 2008) [1–3], extended to an unstructured grid setup....
متن کاملBoundary conditions and estimates for the linearized Navier-Stokes equations on staggered grids
In this paper we consider the linearized Navier-Stokes equations in two dimensions under specified boundary conditions. We study both the continuous case and a discretization using a second order finite difference method on a staggered grid and derive estimates for both the analytic solution and the approximation on staggered grids. We present numerical experiments to verify our results.

An unstructured grid method is presented to compute three-dimensional compressible turbulent flows for complex geometries. The Navier-Stokes equations along with the one equation turbulence model of Spalart-Allmaras are solved using a parallel, matrix-free implicit method on unstructured tetrahedral grids. The developed method has been used to predict drags in the transonic regime for both DLRF...
متن کاملSchwarz domain decomposition for the incompressible Navier-Stokes equations in general co-ordinates
This report describes a domain decomposition method for the incompressible NavierStokes equations in general coordinates. Domain decomposition techniques are needed if we want to solve ows in complex geometries. The discretization is performed by a nite volume method combined with a staggered grid arrangement. The domain decomposition technique is of Schwarz type combined with a GMRES accelerat...
