On the Manipulation of Spreading Rates of Forced Mixing Layers.

Abstract

The vortex merging in a mixing layer can be modified by applying periodic forcing at the origin. When the forcing parameters (frequency, amplitude as well as phase difference between fundamental and subharmonic) varies, the pattern of vortex merging changes. Consequently, the spreading rate of the mixing layer can be manipulated. The effect of each forcing parameter on the change in the spreading is discussed in the present paper. (Author)
