| Description
| - Většina modelů používaných v současné výzkumné praxi pro popis přenosu solí v porézních materiálech je velmi jednoduchá. Tyto modely používají Fickovu difúzní rovnici pro koncentraci solí s konstantním difúzním součinitelem a konstantními počátečními a okrajovými podmínkami. Druhým extrémem v tomto směru jsou plně provázané modely současného přenosu tepla, vlhkosti a chemických látek. Východiskem z problémů vznikajících buď přílišným zjednodušením nebo příliš velkou komplexností je volba rozumného kompromisu, tj. modelu stojícího někde mezi těmito dvěma extrémy. Takové modely jsou ovšem ve výzkumné praxi ještě nepříliš často používány. V tomto článku je jako optimální model identifikována modifikace difúzně-advektivního modelu, která bere v úvahu nejen vliv toku vody na transport soli, ale i vazbu solí na stěnách pórů. (cs)
- Most models applied in current research practice for the description of salt transport in porous materials are very simple. These employ Fick's diffusion equation for the salt concentration with a constant diffusion coefficient and constant initial and boundary conditions. Another extreme in this sense presents a consideration of fully coupled heat, moisture and chemical compounds transport phenomena. A possible way out from the problems arising due to either oversimplification or too high complexity is to choose a reasonable compromise, i.e., a model that is somewhere in between these two extremes. Unfortunately, such models are still rarely used both in the research and technical practice. In this paper, a modification of the diffusion-advection model which takes into account not only the influence of water flow on salt transport but also the effect of salt bonding on pore walls is identified as the most promising for practical applications.
