Controllability of Boussinesq flows driven by finite-dimensional and physically localized forces
Manuel Rissel
We show approximate controllability of Boussinesq flows in driven by finite-dimensional controls that are supported in any fixed reg…

Global controllability of Boussinesq flows by using only a temperature control
Vahagn Nersesyan, Manuel Rissel
We show that buoyancy driven flows can be steered in an arbitrary time towards any state by applying as control only an external temperature profile in a subset of small measure. M…

Relaxation enhancement by controlling incompressible fluid flows
Kai Koike, Vahagn Nersesyan, Manuel Rissel +1
We propose a PDE-controllability based approach to the enhancement of diffusive mixing for passive scalar fields. Unlike in the existing literature, our relaxation enhancing fields…
