Abstract
The effect of introducing a low-frequency periodic mean flow component on the subharmonic growth is investigated. The differences in the development of the fundamental and subharmonic modes under steady and unsteady mean flow conditions are pointed out. The causes behind these differences are investigated using higher order digital analysis techniques. By comparison of the results under steady and unsteady mean flow conditions, we detect the nonlinear interactions that are introduced by the mean flow unsteadiness. The overall effect of mean flow unsteadiness on the transition to turbulence in mixing layers is investigated.
