An analytical study of simultaneous heat and mass transfer in laminar free convection of ternary vapor mixtures on a vertical flat plate is presented. The concentration equations for ternary vapor mixtures. which are coupled to each other, are orthogonally transformed to two uncoupled equations similar to those of binary vapor mixtures. Similarity solutions of the equations under the conditions of zero wall velocity are numerically obtained for practical ranges of dimensionless parameters, namely Prandtl number, Linearized Schmidt number and buoyancy term. Correlation equations for heat and mass transfer are proposed and an example for applying these equations to a condensation problem, of ternary vapor mixtures for the case of negligible heat resistance in the liquid film is expeained. Correlation equations for multicomponent vapor mixtures are also inferentially proposed.
