Analysis of Dual-Time-Stepping with Explicit Subiterations for Advection-Diffusion-Type Equations

چکیده
The purpose of the present paper is to study theoretically the stability and accuracy of dualtime-steppingmethods for the advection-diffusionequation, in conjuctionwith high-order upwindbiased space-discretizations, and high-order backward-differences time-discretizations. These results are in particular analyzed for typical nondimensional time-steps encountered in the simulation of wall-bounded turbulent flows. We attempt to define optimal subiterative strategies (and dual-time-step choice), with respect to stability and accuracy requirements. Typical computational examples are presented.

Space-time radial basis function collocation method for one-dimensional advection-diffusion problem
The parabolic partial differential equation arises in many application of technologies. In this paper, we propose an approximate method for solution of the heat and advection-diffusion equations using Laguerre-Gaussians radial basis functions (LG-RBFs). The results of numerical experiments are compared with the other radial basis functions and the results of other schemes to confirm the validit...
متن کاملPreconditioned Generalized Minimal Residual Method for Solving Fractional Advection-Diffusion Equation
Introduction Fractional differential equations (FDEs) have attracted much attention and have been widely used in the fields of finance, physics, image processing, and biology, etc. It is not always possible to find an analytical solution for such equations. The approximate solution or numerical scheme may be a good approach, particularly, the schemes in numerical linear algebra for solving ...

The nonlinear gyrokinetic equations describe plasma turbulence in laboratory and astrophysical plasmas.

متن کاملNumerical solution of the reaction-advection-diffusion equation on the sphere
A finite volume algorithm for the solution of the reaction–advection–diffusion equation on the sphere is derived and evaluated using analytical solutions. The proposed approach is based on the principle of semidiscretization. The convective and diffusive fluxes are approximated first, and then the resulting set of the ordinary differential equations (ODEs) is solved using the appropriate time s...
