Abstract
[Abstract]: We apply the K-e model to analyse the expansion of a free turbulent jet. Due to nonlinearity of turbulent diffusion the model leads to spatially confined solutions (solutions with finite support). We seek the turbulent energy, dissipation and momentum as power series in spatial coordinate across the jet with timedependent coefficients. The coefficients obey a dynamical system containing slow and fast variables. We show, with the help of numerical analysis, that there exists an attractor for trajectories of the dynamical system, based on a few slow variables.
