Non-isothermal Diffusion of Water Vapour in Porous Building Materials

T. Ficker, Z. Podešvová

Abstract


Non-isothermal diffusion is analysed using Fick's laws. The exact relations for non-isothermal diffusion flux and partial pressure profiles in porous building materials are derived and discussed.

Keywords


Fick's laws; non-isothermal diffusion; partial pressure profile
