Abstract
Pore-scale modeling is appealing for investigating and obtaining macro-scale
constitutive equations for multiphase porous medium systems. These approaches
are based on rigorous physics and bridge the macroscopic and microscopic
scales. In this study, we develop a method to simulate and study the dissolution
of non-aqueous phase liquid (NAPL) blobs. Accurately quantifying NAPL mass
transfer is crucial for modeling decontamination studies faithfully. Nevertheless,
the empirical correlations proposed to date do not transfer from the experimental
porous medium for which they were derived to other media.
We developed a method, in which we simulate a random packing of spheres
and a residual NAPL
