Direct numerical simulation of a planar mixing layer using the spectral-compact finite difference technique
Using a combination of the spectral method and the compact finite difference technique, a numerical algorithm is developed for studying mixing processes in incompressible turbulent fluid flows. The spectral-compact method is fourth order accurate and has good phase error characteristics. The application of this method is illustrated by performing direct numerical simulations of a spatially developing mixing layer. The simulated structure of the developing three-dimensional flow field was found to be similar to the structure observed experimentally.
