Abstract [en]

Detailed studies have been performed to elucidate the mechanisms that govern the gravity-driven free convection condensation of water vapour from binary and ternary mixtures with noncondensable gases. Two major goals of the studies have been to investigate the multidimensional effects and to evaluate the influence of the lighter noncondensable gas in ternary mixtures on the over-all transport phenomena. Two modeling approaches have been used: a solution employing the boundary layer similarity approximation and a numerical solution of multi-fluid, multi-component formulation of the conservation equations. It has been shown that the two approaches are equivalent when applied to binary mixtures in simple geometries. The latter method must be used, howeve, to capture the spatial effects and the ternary mixture phenomena.
