“…5 (Sc = 10, L/H = 4) and an oscillation amplitude corresponding to g/g 0 ∼ 10 −2 at the frequency ω = 0.001 Hz. These are greater than the actual flight values but considerably smaller than the values to be found in the literature [1,[19][20][21]59]. In the instantaneous patterns of the stream function and concentration field isolines and the concentration variation on the boundary over a single oscillation period, periodically formed secondary structures, typical of this kind of flow, are visible (Fig.…”

“…For helping to found and develop this branch in the USSR, great credit must go to Academician V. S. Avduevskii 1 . In connection with this and other applications, we note the development of mass transfer models based on the compressible-gas equations with filtration of the acoustics [18], vibrational convection models (averaged flows induced by non-translational vibration [19]), numerical and experimental studies of low-frequency convection in the presence of vibration [20], the generalization of models of convection under the action of translational and non-translational vibration with account for various complex factors [21], etc.…”

A simulation of 3D convective flows and heat/mass transfer processes under space flight conditions on the basis of hydrodynamic models and a numerical analysis of these models is discussed. The significance of the methods of mechanics in microgravity sciences and the role of the journal "Fluid Dynamics" in the development of this branch of science is examined. The results of recent investigations of certain problems are presented. 3 The title seems to be not quite appropriate since it contains a keyword referring to the notion of "microstructure", which has a different meaning.

“…The results obtained are of interest for the theory of vibrational thermal convection. The average action on a nonisothermal fluid is effective if the cavity is subjected to combined rotational-translational vibration [5,8]. An important case for investigation is the cavity of rectangular cross-section with a large side ratio.…”

The average isothermal fluid flow in an elongated parallelepiped that performs rotational vibration is studied experimentally. The structure and intensity of the average flows and the regularities of their transformation with variation of the vibration frequency are investigated. The dimensionless frequency is varied over a wide interval: from extremely low values where the fluid vibration is largely determined by the viscous forces up to high frequencies where the viscosity is important only in relatively thin Stokes boundary layers. The dimensionless complexes that determine the intensity of the average flows over the entire frequency range are found.

“…At that stage, the component was not taken into account in the calculations. This term was systematically used by several theoretical and experimental works in ground‐based conditions 10–12 . Also, there has been progress in modeling 3D convection, temperature oscillations, and concentration nonuniformity problem for a parallelepiped 13…”

A new model for spatial convective transport processes conjugated with the measured or calculated realistic quasi-steady microaccelerations is presented. Rotation around the mass center, including accelerated rotation, gravity gradient, and aerodynamical drag are taken into account. New results of the effect on mixing and concentration inhomogeneities of the elementary convective processes are presented. The mixing problem in spacecraft enclosures, concentration inhomogeneities due to convection induced by body forces in realistic spaceflight, and the coupling of this kind of convection with thermocapillary convection on the basis of this model are discussed.
