A visualization technique using fluorescein sodium has been developed for the study of mechanical dispersion within fluid-saturated porous media. The measurements were made for single solute-source within the shallow channel where small rectangular blocks were arranged in a periodical fashion. The dilute fluorescein sodium solution was supplied from a single solute-source to the water stream. The color intensity within the field of interest was monitored and then processed to obtain the concentration distribution. Numerical computation results based on the macroscopic mass transfer equation with an adjustable dispersion coefficient was compared against the concentration obtained from the visualization experiment, so as to determine the dispersion coefficient, which provides the best agreement between the numerical and experimental results.
