Assimilation of wall-pressure measurements in direct numerical simulations of high-speed flow over a cone-flare geometry
Pierluigi Morra, Brett Tillman, Stuart Laurence +1
Ensemble-variational (EnVar) assimilation of wall-pressure measurements in direct numerical simulations of Mach 6 flow over a cone-flare is performed. The experimental data include…
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…
Forcing statistics in resolvent analysis: application in minimal turbulent Couette flow
Petrônio A. S. Nogueira, Pierluigi Morra, Eduardo Martini +2
An analysis of the statistics of the non-linear terms in resolvent analysis is performed in this work for turbulent Couette flow at low Reynolds number. Data from a direct numerica…
A realizable data-driven approach to delay bypass transition with control theory
Pierluigi Morra, Kenzo Sasaki, Ardeshir Hanifi +2
The current work presents a realizable method to control streaky disturbances in boundary layer flows and delay transition to turbulence via active flow control. Numerical simulati…
On the role of actuation for the control of streaky structures in boundary layers
Kenzo Sasaki, Pierluigi Morra, André V G. Cavalieri +2
This work deals with the closed-loop control of streaky structures induced by free-stream turbulence in a zero-pressure gradient, transitional boundary layer, by means of localized…
On the relevance of Reynolds stresses in resolvent analyses of turbulent wall-bounded flows
Pierluigi Morra, Onofrio Semeraro, Dan S. Henningson +1
The ability of linear stochastic response analysis to estimate coherent motions is investigated in turbulent channel flow at friction Reynolds number Re = 1007. The analysis is…
