Abstract

The results of a study of convection of moist air in conditions close to atmospheric are presented. Numerical estimates of dimensionless gas-dynamic parameters characteristic of the problem of convection of dry and moist air are presented and analyzed. Distinctive features of convection caused by a change in the concentration of water vapor as a result of its evaporation (condensation) are described. The effect of water vapor concentration on the convective stability of moist air is considered from the point of view of concentration convection, characterized by the concentration Rayleigh number. The technical characteristics of an experimental setup using the principle of holographic interferometry to study the thermoconcentration convection of moist air in the temperature range from 5 to 45 C are shown. The ability to distinguish convective heat and mass transfer in humid air under laboratory conditions is demonstrated.
