Experimental Study of Bimolecular Reactive Transport in a Single Smooth Artificial Fracture

摘要

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