OBSERVATIONS OF THE FORMATION OF STREAMWISE VORTICES

Resumo

Streamwise flow-oriented vortices play an important, if not dominant, role in generating Reynolds stresses. A new mechanism has been identified for forming these vortices. This involves the turning of spanwise arch vortices that occur at locations where the streamwise velocity profile develops a strong inflection.
