Multigrid solution of the Euler equations using implicit ENO schemes

28th Aerospace Sciences Meeting, 1990
In this paper, multigrid technique and implicit E N 0 scheme are combined to yield an efficient and accurate solution procedure for the calculation of steady-state solutions of the Euler equations. The recent developed essentially nonoscillatory schemes have some desirable properties, such as nonoscillatory and uniformly high order even a t critical ...

Unsteady delta-wing flow computation using an implicit factored Euler scheme

1st National Fluid Dynamics Conference, 1988
The conservative unsteady Euler equations for the flow relative motion in the moving frame of reference are used to solve for the steady and unsteady flows around sharp-edged delta wings. The resulting equations are solved by using an implicit approximately-factored finite-volume scheme.

Implicit Kinetic Schemes for the Euler and the Ideal Magnetohydrodynamics Equations

41st Aerospace Sciences Meeting and Exhibit, 2003
The implicit kinetic schemes, namely the Kinetic Flux-Vector Split (KFVS) and the Kinetic Wave/Particle Split (KWPS) schemes are derived for the Euler and the ideal MHD equations. The schemes are applied to compute the flow in a 1-D shock-tube and the 2-D flowfield due to a cylindrical explosion with and without the magnetic field.

Implicit Nonlinear Frequency-Domain Spectral-Difference Scheme for Periodic Euler Flow

AIAA Journal, 2009
This paper combines a nonlinear frequency-domain scheme with a high-order spectral-difference discretization for the two-dimensional unsteady Euler equations. An implicit lower/upper symmetric Gauss-Seidel method is introduced to solve the nonlinear frequency-domain equations.

Multiple-gridding of the Euler equations with an implicit scheme

6th Computational Fluid Dynamics Conference Danvers, 1983
The multiple-grid scheme of Ni (1981) for the solution of the unsteady Euler equations for quasi-one-dimensional transonic flow problems is analyzed according to its ability to accelerate convergence to a steady state solution, its applicability to an implicit scheme, its accuracy, and its stability limits.

Semi-Implicit Euler-Maruyama Scheme for Stiff Stochastic Equations

1996
We discuss a semi-implicit time discretization scheme to approximate the solution of a kind of stiff stochastic differential equations. Roughly speaking, by stiffness for an SDE we mean that the drift coefficient of the considered equtaions satisfies the so-called one-side Lipschitz condition and the diffusion coefficients have the bounded derivatives.

S.K. Godunov's implicit high-accuracy scheme for the numerical integration of Euler's equations

USSR Computational Mathematics and Mathematical Physics, 1987
An implicit version of Gudonov's monotone difference scheme is developed for calculating smooth and discontinuous flows of an ideal gas. The efficiency of this numerical method is demonstrated by application to transonic flows in axially-symmetric nozzles and on a plane grid of symmetric profiles, as well as by comparison with results obtained in ...
