Study on the Resistance Characteristics of Two-Phase Flow through Non-Heat-Generating Porous Media
The steam-water two phase flow resistance in Non-Heat-Generating porous media was studied experimentally and theoretically. The particles-steam drag, particles-water drag and the steam-water interfacial drag were analyzed and the corresponding semi-theoretical models were established. The flow resistance model for one-dimensional two-phase flow consist of void fraction and pressure gradient is been developed using the above drag models with force balances on the two phase. Using the experimental results, the correlations of the void fraction and the interface force were also concluded. The pressure gradient predicted by the flow resistance model is found to agree well with the experimental data. The experimental results were analyzed synthetically to study hydraulic and porous media geometrical parameters influence on two phase flow resistance characteristics. It indicates that both porous media geometrical and hydraulic parameters influence the two-phase flow resistance characteristics greatly, but the porous media geometrical parameters bring in bigger influences.
