Internal layers in turbulent free-shear flows
Daniele Fiscaletti, O. R. H. Buxton, Antonio Attili
Abstract
In turbulent free-shear flows, layers of intense shear bound regions of nearly uniform momentum. The thickness of these layers scales as the Kolmogorov length scale and the velocity across these layers presents a jump of approximately 10% of the characteristic large-scale velocity of the flow. In layers of intense shear, rotation dominates, whereas in layers of intense scalar gradient, strain is prevalent.
