The existing hybrid-scale micro-continuum approach faces difficulties in numerical diffusion issues at the gas-liquid interface and the solid boundary. This article proposes a multiscale compressive Continuum Species Transfer (MC-CST) scheme and a concentration extrapolation algorithm to improve the accuracy of two-phase reactive flow simulations. Furthermore, a case study simulating calcite dissolution in a porous medium is presented to underscore the importance of multiscale fluid-rock interactions for an in-depth comprehension of the dissolution regime.
