Hydrodynamics and heat transfer in turbulent zeromomentum wakes
Abstract
The Reynolds equations and equations describing the diffusion of temperature perturbations in the boundary layer approximation are used to examine the problem of an axisymmetric wake behind a selfpropelled body. The system obtained is closed by means of equations for correlation moments of second order. Selfsimilar solutions for the cross section distribution of mean velocity in the wake and onepoint secondorder moments for velocity pulsations are obtained. Selfsimilar laws are obtained for the damping of scalar quantities in the wake and for the correlations of pulsations of the quantities with velocity pulsations. The theoretical solutions are compared with available experimental data.
