Computational simulation of salt transport and crystallization in limestone depending on the presence of crystallization inhibitor in the dissolved salt is presented. The diffusion-advection model is used for the basic description of coupled water and salt transport, taking into account both water movement due to the moisture gradient and diffusion and dispersion effects within the liquid phase due to the concentration gradient. Salt crystallization in the porous body is modelled using an equilibrium model, taking into account the effect of crystallization inhibition. The effect of salt bonding on the pore walls is taken into account as well. The results of numerical simulations using a well calibrated computational model give evidence that in the analyzed case the use of crystallization inhibitors leads to the slowing down of both water and salt transport.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
