Description

A significant number of transport models have been developed for the simulation of chemical transport in porous media. However, the computational cost can become prohibitively expensive when a problem comprises multiple chemical species; particularly if transport is considered within a significant domain over a long time period. This dataset contains the results produced by a numerical model employing a new indicator-based multi-order problem reduction scheme (PRS) that adresses this issue, as well as those of a full (non-reduced) model. The dataset comprises 6 Excel files, each of which contains predicted chemical concentrations, errors and CPU times of the simulations. The files correspon to: i) a diffusion problem for the validation of the full model, ii) an applicability investigation used to determine the range of applicability of each order of the PRS, iii) a 4 species diffusion problem for the 0th order scheme, iv) a 6 species diffusion problem for the 1st order scheme, v) a 10 species diffusion problem for the 2nd order scheme and vi) a 6 species advection dominant problem for the 1st and 2nd order scheme.
