SIMPLE aerodynamic configurations under even modest conditions can exhibit complex
flows with a wide range of temporal and spatial features. It has become common practice in …

THE field of fluid mechanics involves a range of rich and vibrant problems with complex
dynamics stemming from instabilities, nonlinearities, and turbulence. The analysis of these …

In fluid dynamics, predicting and characterizing bifurcations, from the onset of unsteadiness
to the transition to turbulence, is of critical importance for both academic and industrial …

We use resolvent analysis to design active control techniques for separated flows over a
NACA 0012 airfoil. Spanwise-periodic flows over the airfoil at a chord-based Reynolds …

This work investigates nonlinear dimensionality reduction as a means of improving the
accuracy and stability of reduced-order models of advection-dominated flows. Nonlinear …

We use resolvent analysis to develop a physics-based, open-loop, unsteady control strategy
to attenuate pressure fluctuations in turbulent flow over a rectangular cavity with a length-to …

The stability characteristics of compressible spanwise-periodic open-cavity flows are
investigated with direct numerical simulation (DNS) and biglobal stability analysis for …

The present work investigates sidewall effects on the characteristics of three-dimensional (3-
D) compressible flows over a rectangular cavity with aspect ratios of L/D= 6 and W/D= 2 at R …

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

A comprehensive study of the two-dimensional incompressible shear-driven flow in an open
square cavity is carried out. Two successive bifurcations lead to two limit cycles with different …
