Computation and stability analysis of periodic orbits using finite differences, Fourier or Chebyshev spectral expansions in time
Artur Gesla, Yohann Duguet, Patrick Le Quéré +1
We analyse and compare several algorithms to compute numerically periodic solutions of high-dimensional dynamical systems and investigate their Floquet stability without building t…

Subcritical axisymmetric solutions in rotor-stator flow
Artur Gesla, Yohann Duguet, Patrick Le Quéré +1
Rotor-stator cavity flows are known to exhibit unsteady flow structures in the form of circular and spiral rolls. While the origin of the spirals is well understood, that of the ci…
