A local instability mechanism of the Navier-Stokes flow with swirl on the no-slip flat boundary

Leandro Lichtenfelz, Tsuyoshi Yoneda

Using numerical simulations of the axisymmetric Navier-Stokes equations with swirl on a no-slip flat boundary, Hsu-Notsu-Yoneda [J. Fluid Mech. 2016] observed the creation of a hig…
