Existing correlations for condensation heat fluxes with natural convection from steam-air mixture on a vertical flat plate were compared with existing data in order to select a correlation suitable to use it in computations with a CFD code. Condensation heat fluxes computed with the correlation by Corradini (1984) and the Chilton correlation agreed relatively well with those with natural convection measured in vertical rectangular channels with one-side cooling and changed from forced convection with decreasing mixture velocity.
