Structure of turbulent air motion inside Primary Mirror shaft at Siberian Lidar station of IAO SB RAS. Experiment and simulation

摘要

Structure of air turbulent motion inside Primary Mirror shaft at Siberian Lidar station of V.E. Zuev Institute of Atmospheric Optics SB RAS has been studied. Experiment results performed using ultrasonic weather station are presented. Theoretical results obtained by numerical solving of boundary value problem for hydrodynamics equations (Navier-Stokes). Solitary large vortices (coherent structures, topological solitons) are observed inside the studied room. The coherent decay of such vortices generates a coherent turbulence.
