Air-Water Flow in Coarse Granular Media
Air may be entrained in the flow in porous shore structure under wave action. Three conceptual models for two-phase flow in ducts have been adapted to describe flow in coarse granular media. These are the homogeneous, bubbly drift-flux, and slug drift-flux models. An experimental study was undertaken to check the three models against air-water flow in three coarse granular porous media. The best model was chosen based on its agreement with the experimental head drop results. On this basis the slug flow drift-flux model is recommended to calculate the effect of entrained air on the hydraulic conductivity for co-current and counter current flows.
