A numerical study of boundary-layer heat and mass transfer in a forced flow of humid air with surface steam condensation

Heat and moisture transfer in gaps between sweating imitation skin and nonwoven cloth: effect of gap space and alignment of skin and clothing on the moisture transfer

“…The model had been improved by describing moisture convection induced by vapor pressure gradients and a supersaturation state, and the numerical results showed good agreement with the experimental values for various clothing materials [6][7][8]. Volchkov et al [9] investigated the boundary-layer heat and mass transfer under forced flow of humid air. Li and Zhu [10] developed a dynamic model of heat and liquid water transfer coupled with moisture sorption and condensation in porous textiles.…”

Convective condensation of vapor in the presence of a non-condensable gas of high concentration in laminar flow in a vertical pipe

“…They studied the effect of temperature and concentration boundary conditions on the heat and mass transfer coefficients for different inlet conditions. Volchkov et al [32] obtained numerical solution of the system of differential energy, diffusion, and boundary layer flow equations for the laminar and turbulent flows of humid air with surface steam condensation. Terekhov and Patrikeev [31] and Volchkov et al [32] ignored the thermal resistance offered by the condensate film formed on the duct wall in view of very low condensation rates.…”

Terekhov and Patrikeev [31] and Volchkov et al [32] ignored the thermal resistance offered by the condensate film formed on the duct wall in view of very low condensation rates. Dharma Rao et al [33] tackled theoretically the problem of condensation of water vapor from humid air in turbulent flow in a vertical duct.…”

Mixed Convection Heat and Mass Transfer with Phase Change and Flow Reversal in Channels

“…This term represents the effect of the species diffusion on enthalpy of the humid air mixture. Volchkov et al (2004) reported a numerical work on both laminar and turbulent forced convection of humid air over an infinite flat plate. The authors aim to establish the validity of the heat-mass transfer analogy.…”

“…This technique gives a more accurate estimation of the temperature gradients at the wall (and, hence, the heat transfer coefficient) than Nusselt's theory, which ignores the inertial effects. An interesting way to deal with the liquid film modelling was used by some authors (Lin et al 1988;Yan 1993;Fedorov et al 1997;Volchkov et al 2004;Huang et al 2005;Azizi et al 2007;Laaroussi et al 2009;Oulaid et al 2010b). These authors assumed an extremely thin liquid film so that it could be treated as a boundary condition.…”
