Abstract:
Hydromechanical processes occurring in the viscous flow of gas (air), moving in a narrow channel are considered. It was established that under this case the gas flow by about two-thirds of the length of the channel turbulent, and then becomes laminar and vortex with decreasing rotation vortices speed along longitudinal coordinate. Under the influence of viscous forces around some centers expanding to the periphery the "garland" are formed, it is like having a place in the cosmos. Along the perimeter of a rotating structure are somewhat similar "strings".
Keywords:
numerical simulation, turbulent flow, Reynolds number, galactic structure.
