Simulation of subsonic spatially developing turbulent shear flows

We perform direct numerical simulations of transitional and developed turbulent shear flows. The adequacy of the numerical method is shown in the linear regime of flow perturbations by a comparison between direct numerical simulation and linear stability theory. For this purpose we focus on a two dimensional spatially developing mixing layer. The method is subsequently applied in the nonlinear regime to a simulation of both a separation induced transition and a free shear layer in three dimensions
