Passive stabilization of crossflow instabilities by a reverse lift-up effect
Jordi Casacuberta, Stefan Hickel, Marios Kotsonis
A novel mechanism is identified, through which a spanwise-invariant surface feature (a two-dimensional forward-facing step) significantly stabilizes the stationary crossflow instab…
