On the stability of viscous three-dimensional rotating Couette flow
Michele Coti Zelati, Augusto Del Zotto, Klaus Widmayer
We study the stability of Couette flow in the 3d Navier-Stokes equations with rotation, as given by the Coriolis force. Hereby, the nature of linearized dynamics near Couette flow…

Suppression of lift-up effect in the 3D Boussinesq equations around a stably stratified Couette flow
Michele Coti Zelati, Augusto Del Zotto
In this paper, we establish linear enhanced dissipation results for the three-dimensional Boussinesq equations around a stably stratified Couette flow, in the viscous and thermally…
