Abstract—In this paper, in relation to the problem of reconstructing the evolution of a preplanetary gas and dust cloud, an attempt is made to develop a model of a turbulent heterogeneous medium and to construct on this basis a new class of mathematical models of space media that take into how the character and development of turbulence are influenced by the inertial properties of a polydisperse mixture of dust particles, processes of heat and mass transfer and coagulation, phase transitions, chemical reactions, and radiation. This can significantly expand the capabilities of numerical modeling of various physical phenomena in complex space media such as accretion gas and dust disks formed in stars of various classes during their differential rotation around the center of gravity, to study their structure, physicochemical and hydrodynamic properties, and time evolution.
期刊介绍：
Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
