Experimental Study on Scale Effects for Dispersion Coefficient in a Single Horizontal Fracture
Contaminant transport through fractured media becomes a big issue in environmental engineering.To describe the abnormal flow and transport behaviors in fractured media,well controlled flow experiments and tracer tests have been carded out to study solute transport in a single horizontal fracture under different fracture apertures and flow velocities.Scale effect of the longitudinal dispersion coefficient was found and the fractal dimensions were varied in the range of 0.5-1.8 for solute transport in a single horizontal fracture.The fractal dimension values decrease with the average flow velocity.
