摘要

Numerical simulation and experimental study of bimolecular reactive transport in fracture has significant meaning torngroundwater pollution. In order to study the chemical reaction and the flow condition effects on solute transport, this paper usesrnaniline and 1,2-naphthoquinone-4-sulfonic acid as reactants in a single fracture. The bimolecular reactive transport is conducted inrnsmooth fracture with different flow rates. The main conclusions are drawn: (1) The improved ADRE model can well simulaternreactive solute transport under different flows. The peak concentrations of relative error are lesser by simulation. The simulationrnaccuracy is high. (2) The flow rate also has effect on reactive solute transport. The smaller flow rate is, the better fitting effect.
