Suppressing instabilities in mixed baroclinic flow using an actuation based on receptivity
Abhishek Kumar, Alban Pothérat
This paper presents a method to stabilise oscillations occurring in a mixed convective flow in a nearly hemispherical cavity, using actuation based on the receptivity map of the un…

Pulsatility delays the transition to sustained turbulence in quasi-two-dimensional shear flows
Christopher J. Camobreco, Alban Pothérat, Gregory J. Sheard
This work investigates efficient routes to turbulence in quasi-two-dimensional shear flows. Two-dimensional disturbances require high Reynolds numbers to incite transition from a s…
