   Keywords : transition to turbulence; nonlinear stability analysis; boundary layer flow; övergång till turbulens; icke-linjär stabilitetsanalys; gränsskiktsflöden;

   Abstract : The present thesis studies transition to turbulence in a spatially developing bound-ary layer for subcritical Reynolds numbers. A fully nonlinear iterative direct-adjoint optimisation technique is employed to identify finite amplitude perturbations triggering transition in an energy efficient way. READ MORE
