The density current is a typical fluid flow phenomenon, such as seawater intrusion, condensate discharge, and reservoir siltation. It is of great significant to simulate the infiltration processes and internal structure of density current. In our study, Rhodamine 6G was used to mark high-density brine, and the laser-induced fluorescence technique was used to simulate seawater intrusion. The evolution processes of shearing, oscillating, and mixing at the interface of brine and fresh water, two liquids with different densities, were observed, and the fluorescence intensity of different interfaces was obtained. The concentration distribution was calculated according to the calibration parameters; the concentration nephogram of the three-dimensional concentration fields and cross-sections were obtained to provide a basis for management of seawater intrusion.
