Semi-Implicit Runge-Kutta Schemes For The Navier-Stokes Equations

open access: yes, 1995
. The stationary Navier-Stokes equations are solved in 2D with semi-implicit RungeKutta schemes, where explicit time-integration in the streamwise direction is combined with implicit integration in the body-normal direction. For model problems stability

A Note on Splitting Errors for Advection-Reaction Equations [PDF]

open access: yes, 1994
In this note we consider proper ways to combine numerical schemes for advective transport and nonlinear chemistry. Obvious combinations are obtained with splitting in a so-called fractional step approach.

Exponential Integrators For Quantum-Classical Molecular Dynamics

open access: yes, 1999
. We study time integration methods for equations of mixed quantum-classical molecular dynamics in which Newtonian equations of motion and Schrodinger equations are nonlinearly coupled. Such systems exhibit different time scales in the classical and the

Coupled reaction-diffusion waves in a chemical system via fractional derivatives in Liouville-Caputo sense

open access: yes
In this paper, we have generalized the fractional cubic isothermal auto-catalytic chemical system (FCIACS) with Liouville-Caputo, Caputo- Fabrizio-Caputo, and Atangana-Baleanu-Caputo fractional time derivatives, respectively.

A Morphological Scheme For Mean Curvature Motion And Applications To Anisotropic Diffusion And Motion Of Level Sets.

open access: yes, 1995
. This paper introduces a discrete scheme for mean curvature motion using a morphological image processing approach. After briefly presenting an axiomatic approach of image processing and the mean curvature PDE, the properties of the proposed scheme are ...

Discrete-Time Orthogonal Spline Collocation Methods For Schrödinger Equations In Two Space Variables

open access: yes, 1994
. Two discrete-time orthogonal spline collocation schemes are formulated and analyzed for solving the linear time-dependent Schrodinger equation in two space variables. These are CrankNicolson and alternating direction implicit (ADI) schemes employing C
