文摘

By using unstructured cubic unit mesh with periodic boundary conditions imposed at inlet/right/front surfaces, and FVM, to accomplish high-accuracy simulation of kinetic dissociation phenomena in laboratory-scale sediment samples. To cooperate with molecular simulation, and field-scale simulators, we aim at establishing pore-scale modeling to analyze the simultaneous kinematic process of CO2H dissociation due to non-equilibrium states.
