To Problem on Coefficients of Turbulent Transfer in Gas-Dust Accretion Disk.
Abstract:
The heuristic mode of modelling of factors turbulent interchanging for Keplarian accretion disks arranged around of stars of a solar type is reviewed. The obtained formulas for these factors which are taking into account influence of inverse effects of transfer of dust and a potential temperature on maintaining of a shift turbulence, generalize on protoplanetary gas-dust cloud expression retrieved in classic article (Shaktura, Sunyaev, 1973) for a factor of a diffusion and heat circumscribing at differential rotation of a two-phase mixture flows of a diffusion and heat circumscribing at differential rotation of a two-phase mixture with angular velocity Ω(r,z) transfer of dust and a thermal energy in a direction, perpendicular to an equatorial plane of the disk are deduced. The condition of limiting saturation by small-sized dust alternate corpuscles of a stratum of 'a space liquid', arranged a little bit above (low) subdisk is present.
