Mathematical modeling of bubbles in flow streams and porous media

In many multi-phase chemical and electrochemical reaction systems, the fluid streams with dissolved gas or gas bubbles flow alongside a thin flat sheet of porous medium, composed of materials with varying surface energies. Chemical and electrochemical reactions occur at the surface and interface between the porous material and fluid. As such, the more surface is wetted, the more reaction can proceed, therefore, it is desirable to completely wet the porous material with the liquid phase. However, the gas bubbles and their dynamics can reduce the surface area of the porous material in contact with the liquid phase. The goal of this work is to understand the dynamics of bubble interactions and dissolved gas within the porous material, in order to optimize processes and designs.
