THE MODELING OF REACTIVE SOLUTE TRANSPORT WITH SORPTION TO MOBILE ANDIMMOBILE SORBENTS .2. MODEL DISCUSSION AND NUMERICAL-SIMULATION

We analyze mathematically and numerically a model derived in part 1 of this paper [Kabner et al., this issue]. The model deals with carrier- influenced transport and besides advective and dispersive transport an d equilibrium and nonequilibrium sorption takes into account both carr ier facilitation and cosorption. Guidelines are derived, whether the o verall mobility is enhanced or reduced and various other properties of the model elucidated, in particular for varying carrier concentration s. We indicate how to modify existing numerical codes for the usual ad sorption model and discuss simulations for experimental data sets.
