Growth of perturbations in density stratified plane shear flow
What is it about?
A disturbance in shear flow can grow for a short while even if there are no exponential instabilities. When stable stratification is known to exist, vertical displacement of fluid is inhibited. We examine how much a disturbance can gain in energy in such a stably stratified shear flow.
Why is it important?
We show a buoyancy dominated forcing during the initial stages of the perturbation evolution. Sources of buoyancy are therefore shown to be just as capable as exciting perturbations that can grow transiently.
