Abstract
Numerical simulation of the decay of a momentumless swirling turbulent wake of a body of revolution has been carried out. It has been shown that beginning with the distances of the order of 1000 body diameters, the flow passes to the self-similar regime. Using the results of the numerical analysis of the flow, simplified mathematical models of far wake have been constructed.
