Abstract
Proceeding from the concept of the fractal nature of dust clusters, we develop an evolutionary hydrodynamic model of the formation and growth of loose dust aggregates in an aerodisperse medium of a laminar disk that was originally composed of gas and solid (sub)micron particles. In contrast to a number of classical studies, in which the aggregation process was modeled within an “ordinary” continuous medium and, consequently, the multifractional structure of the dust component of a protoplanetary cloud and the fractal nature of dust clusters being formed during the evolution were often ignored, this paper proposes to consider an ensemble of loose dust aggregates as a special type of a continuous medium, namely, a fractal medium, in which there are points and domains not occupied by dust particles.
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.
