In this study, we simulate the ascending two-phase flow (water and gas) in a vertical porous channel. The flashing phenomenon, which appears when the liquid phase reaches the vaporization conditions during the ascending flow, is being investigated in an isentropic steady state. The mathematical description comes from a separate flow model approach, considering the individual properties of gas and liquid separately. On the other hand, we consider that water and its generated steam make up a mixture characterized by the average properties, according to the mass fraction (i.e., the quality). The capillary pressure and the relative permeability concepts are used. The numerical solution is based on the finite volume method. The semi-implicit algorithm for pressure linking equations is used to predict the detailed flow behavior. Results show that porous media as well as the gas phase flow represent a resistance to the liquid flow. For the same liquid mass flow rate, the pressure of injection increases. In this case, a decrease of the generated steam is observed.
