A mixing-length model for shallow turbulent wakes. (English) Zbl 1057.76027

The goal is to investigate the influence of horizontal diffusion for a range of recirculating wake flows. The basic hypothesis is that vertical turbulent length scales are different, probably smaller, than the horizontal scales. The result can be considered a three-dimensional development of the basic concept of A. K. Rastogi and W. Rodi [AIAA J. 16, 151–159 (1978; Zbl 0394.76058)], now including dispersion and a turbulence model with a simple physical integration. Distributions of vorticity and potential vorticity are considered.
