The process of turbulent natural convection in an innovative reactor-vessel air cooling system subjected to different inlet air/water conditions is studied numerically using an implicit finite-difference method. The problem is formulated by employing a set of modified equations of motion and an upgraded two-equation turbulence model. Results indicate that the effect of humidity is of secondary importance on the performance of the air cooling system. On the other hand, the effect of entrained water droplets can be quite significant, owing to large volumetric change and latent heat effect upon vaporization of the droplets.
