Numerical modelling of condensation had been a challenging task for the researchers for many years due to its time scale and rapidity. Present work deals with the characterization of condensation in presence of non-condensable gases on isothermal surfaces which is a common situation in many condensing devices. The investigation includes the effect of different flow parameters on condensation of saturated steam-air mixture using a numerical approach. The study uses wall condensation model through ANSYS CFX solver. The effect of mass fraction of steam, operating pressure and mass flow rate of mixture is studied. Investigation provides some key characteristics about film condensation which normally remain absent in condensation without non-condensable gas. The findings of this study will provide valuable insight in thermal design process of components incorporating this phenomenon.
