Research Abstract

Large-scale direct numerical simulations and experiments were conducted in two types of plane channel flows, i.e., plane Poiseuille and Couette flows without/with system rotation, in the subcritical-transition regime. Both flows gave rise to coexisting laminar and turbulent equilibrium regions in the form of oblique stripes, which were tilted by a certain angle with respect to the mean flow. In this context, the turbulence stripe can be seen as an intrinsic phenomenon in the reverse transition in a channel flow. It was found that the turbulence stripe should be effective in sustaining turbulence and in heat-transfer enhancement.
