Entrainment of magnetic fluid by a moving boundary of a plane gap
Denis S. Goldobin, Yuriy L. Raikher
A fluid mechanics problem is solved which technological prototype is a fluid acoustic contact that is an inherent element of ultrasonic non-destructive testing procedures. It is we…
Stochastic parametric excitation of convective heat transfer
Evelina V. Permyakova, Denis S. Goldobin
We study the parametric excitation of the free thermal convection in a horizontal layer and a rectangular cell by random vertical vibrations. The mathematical formulation we use al…
Fertilization of liquid-saturated porous medium with multicomponent gases due to surface temperature oscillation
Anastasiya V. Dolmatova, Denis S. Goldobin
We study non-isothermal diffusive transport of a weakly-soluble two-component substance in a liquid-saturated porous medium being in contact with the reservoir of this substance. P…
Comparison of the effect of horizontal vibrations on interfacial waves in a two-layer system of inviscid liquids to effective gravity inversion
Anastasiya V. Dolmatova, Denis S. Goldobin, Tatyana P. Lyubimova
We study the waves at the interface between two thin horizontal layers of immiscible liquids subject to high-frequency tangential vibrations. Nonlinear governing equations are deri…
Specific interface area in a thin layer system of two immiscible liquids with vapour generation at the contact interface
Anastasiya V. Pimenova, Ilias M. Gazdaliev, Denis S. Goldobin
For well-stirred multiphase fluid systems the mean interface area per unit volume, or "specific interface area" , is a significant characteristic of the system state. In parti…
Existence of the passage to the limit of inviscid fluid
Denis S. Goldobin
In the dynamics of viscous fluid, the case of vanishing kinematic viscosity is actually equivalent to the Reynolds number tending to infinity. Hence, in the limit of vanishing visc…
Non-Fickian Diffusion Affects the Relation between the Salinity and Hydrate Capacity Profiles in Marine Sediments
Denis S Goldobin
On-site measurements of water salinity (which can be directly evaluated from the electrical conductivity) in deep-sea sediments is technically the primary source of indirect inform…
Advectional enhancement of eddy diffusivity under parametric disorder
Denis S. Goldobin
Frozen parametric disorder can lead to appearance of sets of localized convective currents in an otherwise stable (quiescent) fluid layer heated from below. These currents signific…
Diffusion of a passive scalar by convective flows under parametric disorder
Denis S. Goldobin, Elizaveta V. Shklyaeva
We study transport of a weakly diffusive pollutant (a passive scalar) by thermoconvective flow in a fluid-saturated horizontal porous layer heated from below under frozen parametri…
Parametric Excitation, Localization and Synchronization in Nonlinear Hydrodynamical Systems
Denis S. Goldobin
The dissertation contains 4 original chapters: 1) Parametric excitation of Soret-driven convection of binary mixture in a horizontal porous layer. 2) Soret-driven convection in a h…
Localization and advectional spreading of convective currents under parametric disorder
Denis S. Goldobin, Elizaveta V. Shklyaeva
We address a problem which is mathematically reminiscent of the one of Anderson localization, although it is related to a strongly dissipative dynamics. Specifically, we study ther…
Large-Scale Thermal Convection in a Horizontal Porous Layer
Denis S. Goldobin, Elizaveta V. Shklyaeva
In a range of physical systems, the first instability in Rayleigh-Bernard convection between nearly thermally insulating horizontal plates is large scale. This holds for thermal co…
