Summary

The formation of fog in laminar and turbulent natural convection boundary layers over a cold vertical surface is investigated theoretically under conditions of local equilibrium, using the similarity forms of the boundary layer equations. The ambient medium surrounding the surface is composed of a noncondensable and a condensable vapour component which is present in trace amounts. The deposition of the vapour species in laminar convection over the cold surface is assumed to occur via ordinary Fick diffusion of vapour plus thermophoretic fog particle drift. In turbulent flow these transport mechanisms are reinforced by the eddy diffusion of vapour and fog particles.
