Abstract

In this paper, we assess effectiveness of using an array of counter-rotating streamwise vortices for transition control in channel flows. We develop models that govern the dynamics of velocity perturbations in the presence of body force excitations and show how changes in control parameters affect perturbation kinetic energy. Effectively, we establish that high frequency streamwise vortices result in the largest energy amplification reduction. Our findings complement a numerical study of Schoppa & Hussain [1] and provide theoretical guidelines for a design of efficient turbulence suppression strategies.
