Townsend has derived a relation between mean vorticity and Reynolds stress valid in the wall layer of a turbulent flow. The vorticity Ω appears as a function of the local stress τ and its gradient. Such a relation is better suited for use in the vorticity equation than in the momentum equation.

Turbulence in shear flow with stability
Journal of Geophysical Research, 1959The turbulence energy balance is considered under conditions of mean-flow shear and varying density stratification, and it is concluded that: in a stable atmosphere the total turbulence energy is reduced; the maximum of the spectrum shifts to smaller scales; and, at heights large compared with the mixing length, the effects of the surface are ...

Turbulent free shear flows occur if there are no walls directly at the flow. Figure 22.1 shows some examples: a free jet, a buoyant jet, a mixing layer with the free jet–boundary flow as a special case, and a wake flow. The corresponding laminar flows are treated in Sects. 7.2, 7.5, 10.5.4 and 12.1.5.

On the Mechanism of Turbulent Shear Flows
Journal of Experimental and Theoretical Physics, 2019As a result of our analysis of some facts of turbulent flows, whose explanation is beyond the scope of existing semiempirical theories, in particular, our estimate of the effective roughness height in pipes with distributed roughness characterized by two or more length scales, we present a version of the theory of turbulent flows in channels with ...
