Abstract
A temporally growing turbulent plane mixing layer is simulated by “Vortex Stick method”, a 3-D Discrete Vortex Method. The growth of large-scale spanwise vortical structures, and the existence of streamwise vortices are observed. How the streamwise vortices are created from the originally spanwise vorticity components is shown : First the vortical segments change their directions, then they are stretched at the braid region in-between the large-scale spanwise vortices.
