Quantitative stability of the 2D Monotone shear flow for Boussinesq equation in a finite channel
Qionglei Chen, Zhen Li
Neither natural nor laboratory laminar flows are perfectly steady. Instead, they are frequently highly unsteady, as illustrated by experimental studies on Bénard convection. In th…

Quantitative stability for the 2D Couette flow on the infinite channel with non-slip boundary condition
Qionglei Chen, Zhen Li, Changxing Miao
In this paper, we investigate the quantitative stability for the 2D Couette flow on the infinite channel with non-slip boundary condition. Compared to the…

The optimal transition threshold for the 2D Couette flow in the infinite channel
Qionglei Chen, Zhen Li, Changxing Miao
We investigate the stability of the 2-D Navier-Stokes equations in the infinite channel with the Navier-slip boundary condition. We show that if the initi…
