On numerical dispersion by upwind differencing
It is shown that any upwind biased scheme for the linear one-dimensional convection equation for the Courant-Friedrichs-Lewy (CFL) number \(\sigma\) in the range [0,1] is free of dispersion if it is applied in one step with CFL number \(\sigma\) followed by a step with CFL number 1-\(\sigma\).
