This
lecture should give an overview over the modelling of mass transfer in porous
media, such as soils or building materials. The main focus is water transport
as a two-phase flow in partially saturated pore systems. The underlying flow
pyhsics, e.g. diffusion and hydraulic conductivity, and their interaction will
be discussed. Main content is:
- Water retention curve
- Sorption isotherm
- Pore volume distribution
- Richards equation
- Mass balance
- Capillary suction
- Knudsen diffusion
- Kelvin equation
