Abstract

The incompressible flow over a forward-facing step is studied. The interest is focused on the characteristics of the global instabilities in this nonparallel shear flow. In particular, the structure of the instability of the flow and the evaluation of the critical Reynolds number have been topics of investigation. The sensitivity of the flow to external disturbances as well as to base flow modifications have been calculated by means of an adjoint analysis, and the main results are reported and discussed. © 2008 Springer-Verlag.
