✦ Synopsis

N e w Jersey Stability criteria are formulated for displacement of a fluid from an infinite porous medium by a second more dense fluid miscible with the fluid being displaced. Pure displacing fluid is separated from pure displaced fluid by a region of constant thickness in which the two fluids interpenetrate. The steady displacement process takes place a t a constont velocity i n the direction of gravity. It i s shown that appreciable differences in pure-component densities, viscosity variation within the zone of interpenetration, and the displacement velocity can have a major effect on the stability criteria of such a flow. * Tabular material has been deposited as document 8153 with the American Documentation Institute, PhotodupIication Service, Library of Congress, Washington 25, D.
