Stability of the Interface Between Two Immiscible Liquids of Unequal Viscosity in a Porous Solid

PDF Version Also Available for Download.

Description

The stability of the interface between two immiscible fluids moving at a uniform rate through a porous medium is investigated. The conditions for stability are derived, and the rate of growing of instabilities of specified wavelength is obtained. The expression for the rate of growth of instability is similar in form to that obtained by Taylor for the case of uniformly accelerated incompressible liquids, but the growth rate is fouud to be inversely proportional to the wavelength rather than inversely proportional to the square root of the wavelength.
