Abstract
In this study the transient development of perturbations in a stratified turbulent shear flow is investigated. The modes with the largest transient growth could be related to the large structures observed in real flows.
This is achieved through the analysis of the temporal stability of the linearized Navier-Stokes equations using the Boussinesq approximation (Kundu & Cohen, 2002). In order to be able to consider turbulent base flows, eddy viscosity and eddy diffusivity approximations are employed. The obtained results are compared to DNS data.
