Accuracy Comparison of High-Order Finite Difference Schemes for the Evolution of Two-Dimensional Finite-Amplitude Disturbances

Abstract

Direct sinrelations of smalland finite-amplitude disturbances in spatially periodic plane Poiseuille flow were performed. The ability of three high-order finite difference methods to predict the proper behavior of the disturbances was under investigation. The proposed procedure allowed to conclude about the spatial resolution and time-step required bv those… (More)
