Investigation of convection in a horizontal cylindrical layer of a saturated porous medium

Publikováno v: Fluid Dynamics. 43:240-247

The structures of the convective motions and the nature of the heat transfer in a horizontal cylindrical layer are studied numerically for the Forchheimer model of a porous medium in the Boussinesq approximation. New asymmetric solutions of the equat

Autor: A. L. Zuev, V. I. Yakushin, V. I. Chernatynskii, R. V. Birikh, V. A. Briskman

Publikováno v: Fluid Dynamics. 29:681-692

Thermal convection in microgravity induced by the combined action of thermocapillary forces and vibrations is considered. In the high-frequency approximation the thermovibrational forces are written for the case in which isothermal mixing of the flui

Convection in mixtures with nonuniform heat release proportional to the density of an active component

Autor: A. K. Kolesnikov, V. I. Yakushin

Publikováno v: Fluid Dynamics. 15:810-816

A study is made of the stability of a horizontal layer of a two-component mixture with concentration gradient of the active (heat releasing) component directed upward. The nature of the instability depends strongly on the direction of the gradient. I

Stability of convective motion caused by inhomogeneously distributed internal heat sources

Autor: V. M. Shikhov, V. I. Yakushin

Publikováno v: Fluid Dynamics. 12:457-461

The stability of steady convective plane-parallel flow in a vertical layer of viscous incompressible liquid of thickness h is investigated. The motion is caused by heat sources distributed in the liquid with volume density Q = Q0exp (−αx) (the x a

Convective instability of a mixture with concentration heat sources

Autor: V. I. Yakushin, A. K. Kolesnikov

Publikováno v: Journal of Engineering Physics. 36:472-477

We investigate the convective stability of a horizontal layer of a two-component binary mixture with internal heat release whose intensity depends on the concentration of one of the components. We present curves of neutral stability and graphs of the

Finite-amplitude convection in mixtures with heat sources proportional to the concentration of one of the components

Autor: A. K. Kolesnikov, V. I. Yakushin

Publikováno v: Fluid Dynamics. 17:821-826

A numerical investigation has been made into the equilibrium stability with respect to finite perturbations of a mixture with heat sources proportional to the concentration of an active component. The convective motions that develop after the loss of
