Laminar and turbulent dispersion of miscible fluids in porous media
The phenomenon of longitudinal dispersion in the flow of miscible fluids through porous media was studied in this investigation. The relationship between the longitudinal dispersion coefficient and the average pore velocity was found experimentally for the three regimes of fluid flow in a porous medium. An equation was developed describing the tracer concentration for the continuous injection of a tracer fluid from a point source in a column of porous medium. The experimental breakthrough curve was used with this equation to find the longitudinal dispersion coefficient as a function of average ...
