Laminar-Turbulent Patterning in Transitional Flows

Laminar-Turbulent Patterning in Transitional Flows

Wall-bounded flows experience a transition to turbulence characterized by the coexistence of laminar and turbulent domains in some range of Reynolds number R, the natural control parameter. This transitional regime takes place between an upper threshold Rt above which turbulence is uniform (featureless) and a lower threshold Rg below which any form of turbulence decays, possibly at the end of o...

Novelty Detection in Laminar and Turbulent Flows

cles in laminar and turbulent flows

Distinct large-scale turbulent-laminar states in transitional pipe flow.

When fluid flows through a channel, pipe, or duct, there are two basic forms of motion: smooth laminar motion and complex turbulent motion. The discontinuous transition between these states is a fundamental problem that has been studied for more than 100 yr. What has received far less attention is the large-scale nature of the turbulent flows near transition once they are established. We have c...
