Direct numerical simulation of transition under free-stream turbulence and the influence of large integral length scales
Kristina Đurović, Ardeshir Hanifi, Philipp Schlatter +2
Under action of free-stream turbulence (FST), elongated streamwise streaky structures are generated inside the boundary layer, and their amplitude and wavelength are crucial for th…
Improved convergence of the spectral proper orthogonal decomposition through time shifting
Diego C. P. Blanco, Eduardo Martini, Kenzo Sasaki +1
Spectral proper orthogonal decomposition (SPOD) is an increasingly popular modal analysis method in the field of fluid dynamics due to its specific properties: a linear system forc…
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…
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…
