In this work, numerical analyses accompanied with experimental validations are conducted in the aim of the investigation of the vapor condensation and steam-air mixture phenomena. An experimental apparatus is built for the facilitation of measurements and reproduction of real condensation occurrences under sub-atmospheric pressure. During experiments, the heat transfer characterization is presented in co and counter current vapor configurations. In the co-current configuration, the non-condensable gas is investigated for vertical and inclined tubes. The results show that the heat transfer is enhanced by inclining the tube 45 to 90° from the horizontal level. Plus, some experiments were done to characterize the heat exchange for vapor condensation in counter-current configuration. The experimental results show that the vapor velocity should be limited under certain values to prevent the disturbing of the liquid film flow. This phenomenon, which is considered like an indication for the creation of flooding phenomenon, was studied using an additional experimental apparatus built during the thesis work. It permits determining the limit velocity associated to the flooding phenomenon for a counter-current air-water flow. Three physical limits have been recognized thanks to pressure drop, and for different water flow rates, and tube inclinations. Furthermore, a physical model that takes into account the presence of air and permits modeling the condensation phenomenon in sub-atmospheric pressure for the two configurations studied experimentally is presented. This model comprises the diffusion boundary layer theory by combining of the momentum, heat and mass balance equations
