How's the diffusivity equation written and solved in two-phase gas/liquid flow?

the diffusivity equation describes pressure profile during flow of fluids through porous media. this equation is normally written for single phase flow, i.e. either oil or gas flow. However, there...

How can the interfacial tension (or surface tension) be affected by pore geometry and pore diameter in a porous medium?

The interfacial tension is normally regarded as a fluid property. However, I think there could be some relationship between this property and rock characteristics in the pore scale.
