| Research Abstract |
The two-phase mixture model, proposed by Wang and Beckermann for single component two-phase flows, has been extended to a general model, which can deal with multi-component multi-phase flows associated with underground water contamination.
First, Forchheimer's modification was implemented in the model to develop a computer simulation code for predicting mass and heat transfer in single-component two-phase flows, in which the porous inertia is not negligible. Pool boiling in a cavity and mixed convection boiling in a channel, both filled with solid spheres were investigated numerically to verify the computer simulation code.
In order to deal with underground multi-component multi-phase flows, the model was modified extensively, such that mass, momentum and energy balances for individual components and phase are conserved. These conservation equations for multi-component multi-phase flows were solved numerically along with auxiliary relationships such as Forchheimer-extended Darcy's law, equilibrium phase diagram, Leverett and hindrance functions.
