Journal ArticleDOI
Implicit schemes and LU decompositions
Antony Jameson,Eli Turkel +1 more
TL;DR: In this paper, it was shown that the solution of tridiagonal hyperbolic systems in one dimension is well conditioned if and only if the LU factors are diagonally dominant.
Journal ArticleDOI
Far field boundary conditions for compressible flows
Alvin Bayliss,Eli Turkel +1 more
TL;DR: In this article, a family of boundary conditions which simulate outgoing radiation are derived and applied to the computation of steady state flows and are shown to significantly accelerate the convergence to steady state.
Journal ArticleDOI
On accuracy conditions for the numerical computation of waves
TL;DR: It will be shown that the number of points per wavelength, measured by ( Kh ) −1 , is not sufficient to determine the accuracy of a given discretization, and the quantity K 3 h 2 is shown to determined the accuracy in the L 2 norm for a second-order discretized method applied to several propagation models.
Journal ArticleDOI
An Iterative method for the Helmholtz equation
TL;DR: An iterative algorithm for the solution of the Helmholtz equation is developed based on a preconditioned conjugate gradient iteration for the normal equations.
Proceedings ArticleDOI
Artificial dissipation and central difference schemes for the Euler and Navier-Stokes equations
R. C. Swanson,Eli Turkel +1 more
TL;DR: In this paper, an artificial dissipation model, including boundary treatment, that is employed in many central difference schemes for solving the Euler and Navier-Stokes equations is discussed.
