von Neumann stability conditions for the convection-diffusion eqation
Delft University of Technolgy, Faculty of Technical mathematics and Informatics P O Box 5031, 2600 GA Delft, The Netherlands
A method is presented to easily derive von Neumann stability conditions for a wide variety of time discretization schemes for the convection-diffusion equation. Spatial discretization is by the K-scheme or the fourth-order central scheme. The use of the method is illustrated by application to multistep, Runge-Kutta and implicit-explicit methods, such as are in current use for flow computations, and for which, with few exceptions, no sufficient von Neumann stability results are available.
