The transport of heat and moisture in porous structures still presents fundamental problems of understanding. In a first attempt, the existing equations have been thoroughly investigated to exploit their potential. Some interesting results could be obtained:
|
- An important ambiguity in the description of non-linear heat and moisture fields. (Res. Rep. Nr. 3/97)
- A complete and final discussion of capillary dynamics. (Res. Rep. Nr. 4/97)
- A reformulation and solution of the Ljukov system of equations by so-called "diffusors". (Res. Rep. Nr. 4/97 and Heat and Mass Transfer 35, 49-52 (1999))

An outcome of this work is the commencement of the new project "Heat and moisture transport in fractal structures".
|
The goal:
|
Clarifying and understanding the existing phenomenological equations for heat and moisture transport in porous structures.
