Phase-based analysis and control of supersonic turbulent cavity flows
Vedasri Godavarthi, Yoji Kawamura, Lawrence S. Ukeiley +2
We present a phase-based framework for reducing the pressure fluctuations within a spanwise-periodic supersonic turbulent cavity flow with an incoming free-stream Mach number of 1.…
Pressure-Informed Velocity Estimation in a Subsonic Jet
Songqi Li, Lawrence Ukeiley
This work aims to estimate time-resolved velocity field that is directly associated with pressure fluctuations in a subsonic round jet. To achieve this goal, synchronous measuremen…
Spectral Analysis Modal Methods (SAMMs) using Non-Time-Resolved PIV
Yang Zhang, Louis N. Cattafesta, Lawrence Ukeiley
We present spectral analysis modal methods (SAMMs) to perform POD in the frequency domain using non-time-resolved Particle Image Velocity (PIV) data combined with unsteady surface…
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…
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,…
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…
