Global stability of rigid-body-motion fluid-structure-interaction problems
Prabal S. Negi, Ardeshir Hanifi, Dan S. Henningson
A rigorous derivation and validation for linear fluid-structure-interaction (FSI) equations for a rigid-body-motion problem is performed in an Eulerian framework. We show that the…
Unsteady aerodynamic effects in small-amplitude pitch oscillations of an airfoil
Prabal S. Negi, Ricardo Vinuesa, Ardeshir Hanifi +2
High-fidelity wall-resolved large-eddy simulations (LES) are utilized to investigate the flow-physics of small-amplitude pitch oscillations of an airfoil at Re = 100,000. The inves…
Turbulent boundary layers around wing sections up to Rec = 1,000,000
R. Vinuesa, P. S. Negi, M. Atzori +3
Reynolds-number effects in the adverse-pressure-gradient (APG) turbulent boundary layer (TBL) developing on the suction side of a NACA4412 wing section are assessed in the present…
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…
