Conservative correction of the sequential noniterative scheme for reactive transport problems with minerals precipitation–dissolution and variable media properties

The aim of this work is the substantiation of the applicability of the splitting scheme to the solution of reactive transport in porous media problems involving precipitation–dissolution reactions and variable media porosity. The reasons why this scheme was abandoned for modelling this type of problems in the previous works are analyzed. We consider a corrected scheme featuring mass conservation and convergence. It is tested on problems with analytical solutions and its performance is shown on a benchmark of the dissolution of concrete minerals.
