Optimal Transient Growth in an Incompressible Flow past a Backward-Slanted Step

Optimal Transient Growth in an Incompressible Flow past a Backward-Slanted Step

With the aim of providing a first step in the quest for a reduction of the aerodynamic drag on the rear-end of a car, we study the phenomena of separation and reattachment of an incompressible flow by focusing on a specific aerodynamic geometry, namely a backward-slanted step at 25<inline-formula...
