Abstract
Numerical analysis of the swirling turbulent wake degeneration past a self-propelled body has been carried out. It has been shown that starting from the distances of the order of 100 diameters from the body, the flow becomes prac-tically shearless. A simplified mathematical model of the far swirling wake past a self-propelled body has been constructed.
