Abstract
In the presented work, in relation to the problem of reconstructing the evolution of an exoplanetary gas-dust cloud, a model of a turbulent heterogeneous medium is developed, on the basis of which it is possible to create a new class of numerical models of space gas-dust media, taking into account the influence on the nature and development of turbulence of the inertial properties of a polydisperse dust phase, heat and mass transfer processes, coagulation, chemical reactions and radiation. This makes it possible to signifi-cantly expand the possibilities of numerical modeling of various physical and chemical phe-nomena in such cosmological objects as accretion gas and dust disks formed in stars of var-ious classes during their differential rotation around the center of gravity and, in particular, to study their structure. physicochemical and hydrodynamic properties and time evolution.
