Title:Viscous instability of the stable Poiseuille flow
Seminar:CCMA Luncheon Seminar
Speaker:Toan Nguyen, Penn State
Abstract Link:
I'll present a new, operator-based approach to establish spectral instability of generic plane shear profiles (hence, including those which are stable under corresponding Euler flows) in the 2D incompressible Navier-Stokes flows with small viscosity. Such a viscous destabilization phenomenon has been well-documented in the physical literature, going back to works of Heisenberg, C.C. Lin, Tollmien, and other prominent physicists.
