Авторы: Marov M., Kolesnichenko A.
Space exploration and advanced astronomy have dramatically expanded our knowledge
of outer space and made it possible to study the indepth mechanisms underlying various
natural phenomena caused by complex interaction of physical-chemical and dynamical
processes in the universe. Huge breakthroughs in astrophysics and the planetary sciences
have led to increasingly complicated models of such media as giant molecular
clouds giving birth to stars, protoplanetary accretion disks associated with the solar
system’s formation, planetary atmospheres and circumplanetary space. The creation of
these models was promoted by the development of basic approaches in modern mechanics
and physics paralleled by the great advancement in the computer sciences. As a
result, numerous multidimensional non-stationary problems involving the analysis of
evolutionary processes can be investigated using wide-range numerical experiments.
Turbulence belongs to the most widespread and, at the same time, the most complicated
natural phenomena, related to the origin and development of organized structures (eddies
of different scale) at a definite flow regime of fluids in essentially non-linear hydrodynamic
systems. This is also one of the most complex and intriguing sections of the
mechanics of fluids. The direct numerical modeling of turbulent flows encounters large
mathematical difficulties, while the development of a general turbulence theory is
hardly possible because of the complexity of interacting coherent structures.
