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…
