Abstract

This study describes the Floquet stability analysis of the wake flow behind a mechanically oscillated circular cylinder placed in a low Reynolds-number flow. After defining the base flow, three-dimensional perturbation is introduced into the flow. The governing equations for the evolution of disturbance are derived. The integration of the linearised perturbation equations is carried out in the same way as for the base flow. The Floquet multiplier, which indicates whether the flow is stable or not, is determined using Krylov subspace iteration. The code developed for the Floquet analysis is still being tested.
