Description

By measuring the thermo-molecular pressure difference and using principles of irreversible thermodynamics, heat of transport of air in clay and its coefficient of diffusion are found. A comparison of thermo-transpiration and pressure driven gas fluxes through concrete slab in homes is examined. It is shown that thermo-transpiration air/radon flow may greatly exceed diffusion (pressure driven) flow in homes. (authors)
