Resolvent analysis of compressible laminar and turbulent cavity flows

Yiyang Sun, Qiong Liu, Louis N. Cattafesta +2

The present work demonstrates the use of resolvent analysis to obtain physical insights for open-cavity flows. Resolvent analysis identifies the flow response to harmonic forcing,…

Feedback control for transition suppression in direct numerical simulations of channel flow

Yiyang Sun, Maziar S. Hemati

For channel flow at subcritical Reynolds numbers (), a laminar-to-turbulent transition can emerge due to a large transient amplification in the kinetic energy of small per…

Modal Analysis of Fluid Flows: Applications and Outlook

Kunihiko Taira, Maziar S. Hemati, Steven L. Brunton +5

We present applications of modal analysis techniques to study, model, and control canonical aerodynamic flows. To illustrate how modal analysis techniques can provide physical insi…

Active attenuation of a trailing vortex inspired by a parabolized stability analysis

Adam M. Edstrand, Yiyang Sun, Peter J. Schmid +2

Designing effective control for complex three-dimensional flow fields proves to be non-trivial. Oftentimes, intuitive control strategies lead to suboptimal control. To navigate the…

Spanwise effects on instabilities of compressible flow over a long rectangular cavity

Yiyang Sun, Kunihiko Taira, Louis N. Cattafesta +1

The stability properties of two- (2D) and three-dimensional (3D) compressible flows over a rectangular cavity with length-to-depth ratio of is analyzed at a free stream Mac…

Effects of sidewalls and leading-edge blowing on flows over long rectangular cavities

Yiyang Sun, Qiong Liu, Louis N. Cattafesta +2

The present work investigates sidewall effects on the characteristics of three-dimensional (3D) compressible flows over a rectangular cavity with aspect ratios of and $W/D=…
