Transition threshold for the 3D Couette flow in a finite channel

Qi Chen, Dongyi Wei, Zhifei Zhang

In this paper, we study nonlinear stability of the 3D plane Couette flow $(y, 0, 0)$ at high Reynolds number $R e$ in a finite channel $T \times [- 1, 1] \times T$ . It…

On the $L^{\infty}$ stability of Prandtl expansions in Gevrey class

Qi Chen, Di Wu, Zhifei Zhang

In this paper, we prove the $L^{\infty} \cap L^{2}$ stability of Prandtl expansions of shear flow type as $(U (y / ν), 0)$ for the initial perturbation in the Gevrey class, whe…
