Generalised nonlinear stability of stratified shear flows: adjoint-based optimisation, Koopman modes, and reduced models
(Department of Applied Mathematics and Theoretical Physics, University of CambridgeUniversity of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsSt John's College, 2016-10-04)In this thesis I investigate a number of problems in the nonlinear stability of density stratified plane Couette flow. I begin by describing the history of transient growth phenomena, and in particular the recent application ...
