title = "Stability of time-averaged cylinder wake and receptivity to inlet flow pulsation",
abstract = "In this paper, the linear stability analysis (LSA) is utilized to investigate the stability of time-averaged cylinder wake past a circular cylinder at Re = 200 and its receptivity to inlet flow pulsation. An in-house finite volume method is used to solve the full N-S equations as well as the linearised set for small perturbations around the time-averaged flow. The solution of the latter set provides information about the stability of the wake. It is found that the most unstable eigenmode has a small negative real part and an imaginary part that closely marches the Strouhal number of vortex shedding. This finding agrees with the results of other investigators. Inlet flow pulsation appears as a forcing term in the linearised equation set. Both cross-stream and streamwise velocity components in the separating shear layers are strongly affected by pulsation. The effect of pulsation is spatially localised in the near wake. Increasing the pulsation frequency reduces the spatial extent within which pulsation plays an important role.",
