Resumo
The hydromechanical processes occurring in the viscous flow of a gas (air), moving in a narrow channel are considered. In this case the gas flow is found to remain turbulent for about two-thirds of the channel length, after which it becomes laminar and vortex with the vortex rotation speed decreasing along the longitudinal coordinate. The “strings” expanding toward the periphery arise around some centers under the influence of viscous forces not unlike those in outer space. Several similar strings are located along the perimeter of such a rotating structure.
