Abstract

Coherent structures (topological solitons) indoors had been simulated by numerical solving of hydrodynamics equations. "Indoors" means inside the closed volume without the external direct wind influence and without the exchange of internal and external medium through the borders. Results of six boundary value problems are demonstrated: spectrograph pavilion and telescope dome of large astronomical telescopes (LSVT and BTA), cubic room, flat square cuvette, square section tube, parietal turbulence (thermals). The solitary large vortices (coherent structures, topological solitons) are observed indoors. The scenes of air motion as a result of simulation of coherent structures with identical boundary conditions are the practically same as the scenes, independently previously registered at experiments by us (indoors LSVT and BTA).
