Linear instability of low Reynolds number massively separated flow around three NACA airfoils
Two- and three-dimensional modal and non-modal instability mechanisms of steady spanwise-homogeneous laminar separated flow over airfoil profiles, placed at large angles of attack against theExpand

A DYNAMICAL SYSTEM ASSOCIATED WITH NEWTON ’ S METHOD FOR PARAMETRIC APPROXIMATIONS OF CONVEX MINIMIZATION PROBLEMS
We study the existence and asymptotic convergence when t → +∞ for the trajectories generated by ∇f(u(t), (t))u̇(t) + ̇(t) ∂2f ∂ ∂x (u(t), (t)) +∇f(u(t), (t)) = 0 where {f(·, )} >0 is a parametricExpand

Instability and sensitivity analysis of flows using OpenFOAM
TLDR
The present contributions deal with the development and implementation of the direct and adjoint incompressible Navier–Stokes equations in a matrix-free time-stepping context making use of the open-source OpenFOAM® (open source field operation and manipulation) C++ toolbox. Expand

On the use of matrix-free shift-invert strategies for global flow instability analysis
A novel time-stepping shift-invert algorithm for linear stability analysis of laminar flows in complex geometries is presented. This method, based on a Krylov subspace iteration, enables the solutionExpand
