Hydrodynamic dispersion in porous materials
Journal Article

· Soil Sci.; (United States)
This study considers some aspects of the hydrodynamic dispersion of tracer which occurs under the combined influence of molecular diffusion and convection when a fluid flows through a finite column of porous material. In particular, the study discusses (1) the use of the principle of superposition to obtain breakthrough curves for pulsed and periodic inputs of tracer, (2) the form of dispersion coefficients in terms of dimensionless groups of parameters, and (3) the mechanism underlying dispersion.
