Abstract

This paper describes a study of transition in Couette flow initiated by the transient growth mechanism. It is shown that four modes obtained analytically are sufficient to model the transient growth. The analytical approximation allows performing a secondary stability analysis of the modified baseflow consisting of the Couette flow and a transient growth perturbation. The predictions of the secondary stability analysis are verified by checking whether transition occurs in a direct numerical simulation (DNS) initiated by the analytical expressions. Finally, the capability of the analytical expressions to capture some of the transition stages is tested.
