A model for limit-cycle switching in open cavity flow
Prabal S. Negi
A reduced mathematical model for the flow in an open cavity is presented. The reduction is based on the center manifold theory applied to a perturbation of the original system whic…
Structure Preserving Restarts of the Non-Symmetric Lanczos Algorithm via the Implicitly shifted LR algorithm
Prabal S. Negi, Cristobal Arratia
The implicitly shifted QR iteration is used as a restart procedure for the Arnoldi method for the calculation of a few dominant eigenvalues of a large matrix. We show that the unde…
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…
Reynolds-number effects in turbulent boundary layers around wing sections
Ricardo Vinuesa, Prabal Negi, Marco Atzori +3
Four well-resolved LESs of the turbulent boundary layers around a NACA4412 wing section, with Rec ranging from 100,000 to 1,000,000, were performed at 5 degree angle of attack. By…
