Approximate Solution to a Model of the far Momentumless Axisymmetric Turbulent Wake

The flow in the far axisymmetric momentumless turbulent wake is described with the use of a mathematical model based on k - E semi -empirical model of turbulence. A group -theoretical analysis of the mathematical model of the wake is performed. The similarity reduction of the model to a system of ordinary differential equations is obtained. Asymptotic expansion of the solution in the vicinity of a singular point is used to construct approximate solution of corresponding boundary value problem.
