On the Spectral Properties of Shock-Capturing Schemes

Journal of Computational Physics, 2006
In this short note we analyze the performance of nonlinear, shock-capturing schemes in wavenumber space. For this purpose we propose a new representation for the approximate dispersion relation which accounts to leading order for nonlinear effects. Several examples are presented, which confirm that the present theory yields an improved qualitative ...

Shock Capturing with Discontinuous Galerkin Method [PDF]

, 2006
Shock capturing has been a challenge for computational fluid dynamicists over the years. This article deals with discontinuous Galerkin method to solve the hyperbolic equations in which solutions may develop discontinuities in finite time. The high order discontinuous Galerkin method combining the basis of finite volume and finite element methods has ...

Shock-Capturing Algorithm for the Navier-Stokes Equations

AIAA Journal, 1981
An implicit numerical algorithm for the unsteady Euler and Navier-Stokes equations is presented. This algorithm is based on flux vector splitting to retain the proper direction of information flow in the algorithm's numerical domain of dependence and on a finite volume formulation to ensure conservation.

Shock-Capturing Approach and Nonevolutionary Solutions in Magnetohydrodynamics

Journal of Computational Physics, 1996
The authors show the possibility of non-evolutionary or unstable solutions in magnetohydrodynamics when using the shock capturing model. The results obtained are compared with earlier results and are shown to be better ones.

Shock-capturing schemes for L.E.S. applications

2008
Numerical simulations of freely decaying isotropic turbulence were performed at two different Mach numbers (0.2 and 1.0) using known shock-capturing Euler schemes (Jameson, TVD-MUSCL, ENO). The potential of the Monotone Integrated Large-Eddy Simulation (MILES) approach was investigated by carrying out computations without viscous diffusion terms. These

Projection shock capturing algorithms

2008
discretized in time and space with step sizes At, £xx and Ay, t~ = n a t , xj = j£xx, Yk = kay. The numerical solution in the point (t~, xj, Yk) is denoted by uj~ and the entire solution at t ime t~ is u ~ and a function of j, k. We consider the solution of the above problem with finite difference methods.
