text: Most flows in nature and engineering are turbulent because of their large
velocities and spatial scales. Laboratory experiments on rotating quasi-Keplerian
flows, for which the angular velocity decreases radially but the angular momentum
increases, are however laminar at Reynolds numbers exceeding one million. This
is in apparent contradiction to direct numerical simulations showing that in these
experiments turbulence transition is triggered by the axial boundaries. We here
show numerically that as the Reynolds number increases, turbulence becomes progressively
confined to the boundary layers and the flow in the bulk fully relaminarizes.
Our findings support that turbulence is unlikely to occur in isothermal constant-density
quasi-Keplerian flows.
