Miscible-liquid displacements of water/ethanol solutions were conducted in a 2.54-cm-ID column packed with glass beads of 275 to 300 and 25 to 30 mesh with bed heights of 6.35 to 40.8 cm. The viscosity ratio of the resident fluid to displacing fluid was maintained at 0.72 for fluid pairs with favorable density differences. Dispersion coefficients obtained from a two-parameter model increased from approx.3 x 10/sup -5/ to approx.2 x 10/sup -2/ cm/sup 2//s with increasing packing particle size, fluid velocity, and density difference.
