Wavepacket Modelling of Broadband Shock-Associated Noise in Supersonic Jets
Marcus H. Wong, Peter Jordan, Igor A. Maia +4
We present a two-point model to investigate the underlying source mechanisms for broadband shock-associated noise (BBSAN) in shock-containing supersonic jets. In the model presente…
Causality in the shock wave/turbulent boundary layer interaction
Kenzo Sasaki, Diogo C. Barros, André V. G. Cavalieri +1
The mechanisms governing the low-frequency unsteadiness in the shock wave/turbulent boundary layer interaction at Mach 2 are considered. The investigation is conducted based on the…
Structure interactions in a reduced-order model for wall-bounded turbulence
André V. G. Cavalieri
New reduced-order models (ROMs) are derived for sinusoidal shear flow (also known as Waleffe flow) and plane Couette flow in small periodic domains. A first derivation for Waleffe…
Resolvent-based estimation of turbulent channel flow using wall measurements
Filipe R. Amaral, André V. G. Cavalieri, Eduardo Martini +2
We employ a resolvent-based methodology to estimate velocity and pressure fluctuations within turbulent channel flows at friction Reynolds numbers of approximately 180, 550 and 100…
Closed-loop control of forced turbulent jets
Igor A. Maia, Peter Jordan, André V. G. Cavalieri +2
Closed-loop control of turbulent flows is a challenging problem with important practical and fundamental implications. We perform closed-loop control of forced, turbulent jets base…
The colour of forcing statistics in resolvent analyses of turbulent channel flows
Pierluigi Morra, Petronio A. S. Nogueira, André V. G. Cavalieri +1
The cross-spectral density (CSD) of the non-linear forcing in resolvent analyses is here quantified for the first time for turbulent channel flows. Direct numerical simulations (DN…
