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
