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…

Local exact Lagrangian controllability for 1D barotropic compressible Navier--Stokes equations
Kai Koike, Franck Sueur, Gastón Vergara-Hermosilla
We consider a viscous compressible barotropic flow in the interval with homogeneous Dirichlet boundary conditions for the flow velocity and a constant rest state as initial…
