Global stability analysis of flow behind an upswept aftbody
Qiong Liu, Datta V. Gaitonde, Rajesh Ranjan
Wakes of aircraft and automobiles with relatively flat slanted aftbodies are often characterized by a streamwise-oriented vortex pair, whose strength affects drag and other crucial…
Acoustic response of turbulent cavity flow using resolvent analysis
Qiong Liu, Datta Gaitonde
The decomposition of hydrodynamic and acoustic components of cavity flows can aid the understanding of the flow-acoustic interaction, which produces a variety of adverse effects in…
Unsteady control of supersonic turbulent cavity flow based on resolvent analysis
Qiong Liu, Yiyang Sun, Chi-An Yeh +3
We use resolvent analysis to determine an unsteady active control setup to attenuate pressure fluctuations in turbulent supersonic flow over a rectangular cavity with a length-to-d…
Active flow control of a pump-induced wall-normal vortex with steady blowing
Qiong Liu, Byungjin An, Motohiko Nohmi +2
The emergence of a submerged vortex upstream of a pump can reduce pump intake efficiency and cause structural damage. In this study, we consider the use of active flow control with…
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,…
Core-pressure alleviation for a wall-normal vortex by active flow control
Qiong Liu, Byungjin An, Motohiko Nohmi +2
We consider the application of active flow control to modify the radial pressure distribution of a single-phase wall-normal vortex. The present flow is based on the Burgers vortex…
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=…
