Abstract

This paper describes a laminar to turbulent transition scenario in Couette flow, triggered by the transient growth mechanism. An analytical derivation of a growing disturbance corresponding to counter rotating vortices embedded in Couette flow allows performing a secondary linear stability analysis of the perturbed flow. Based on the comparison with direct numerical simulation results, it is argued that a significant transient growth is not a prerequisite for transition and that the role of the initial transient growth is to generate a strong wall-normal inflectional point rather than maximal growth.
