    Abstract

    A direct numerical simulation of transitional and developed turbulent flow in a three-dimensional spatially developing subsonic mixing layer is performed. The time-averaging of the solution yielding, for example, the momentum thickness is considered and it is shown that this averaging should be performed over at least four to seven ‘traversal’ time units to obtain sufficient accuracy. The resulting growth rate is determined and compared with results from physical experiments. The developed turbulent flow displays characteristics of self-similarity.
