A Numerical Study of Combined Heat and Mass Transfer in an Inclined Channel Using the VOF Multiphase Model

Turbulent conjugate heat and mass transfer from the surface of a binary mixture of ethanol/iso-octane in a countercurrent stratified two-phase flow system

“…The use of such user defined variables has been previously used by the author [36,37] in studying evaporation of pure fluids. As these variables are solvable in the whole flow domain, in the first study [36], saturated vapour mass fraction was assigned in the liquid phase using the concept of ''internal" boundary condition [38].…”

“…However, sensible and latent heat transfer was neglected in this study. In the second study [37], these restrictions were removed with the actual calculation of interfacial mass transfer from the gradient of the user defined variable at the liquid/gas interface. The present study is an extension of the last study by taking into account heat and mass transfer of non-ideal liquid mixtures.…”

Evaluation of gasoline evaporation during the tank splash loading by CFD techniques

“…This approach was similar to Banerjee's work for calculation of evaporation rate [17]; however Banerjee used the concept of internal boundary condition [24] and used the scalar transport equation for calculation of evaporation flux. In Banerjee algorithm the mass fraction set to zero in all cells that completely filled with liquid after flux calculation.…”

“…Based on literature reviews [13][14][15][16], the surface tracking methods has been mainly used to study the heat and mass transfer of droplets and bubbles, but a few studies has been done on complex flows. Banerjee has used the VOF method to study heat and mass transfer of stratified flow through the automotive filler pipe [17,18]. Fuel splash loading is a complex phenomenon that involves unsteady multiphase turbulent flow conjugated with heat and mass transfer.…”

Computational fluid dynamics simulations of direct contact heat and mass transfer of a multicomponent two-phase film flow in an inclined channel at sub-atmospheric pressure

“…Considering the heat and mass transfer at the gas-liquid interface in an inclined channel, Banerjee [8,9] investigated the evaporation of methanol and ethanol/isooctane mixtures. The evaporation rate was determined by the diffusion flux of gas species at the gas-liquid interface in the form of Fick's Law, and turbulence was treated using the renormalization group k-e turbulence model.…”
