Abstract

The effects of the low-frequency variations in the mean flow on the transition of mixing layers are examined. The results show that, in both steady and unsteady mixing layers, low-frequency modes play an important role in the transition by enhancing energy transfer to the sidebands. Yet, when low-frequency variations are introduced in the mean flow, a broader and richer array of energy transfer, that involve the low-frequency component, takes place which causes more efficient energy transfer to the sidebands.
