✦ Synopsis
Flow of Dilute, Stable Liquid and Solid Dispersions in Underground Porous Media 0.5 Suspensions of 0.5 vol. % (c, = 0.005) are injected continuously into a quartz sandpack of initial permeability KO = 1.15 pm2 at a constant superficial velocity of u = 0.07 mm/s. The mean grain size from sieve analysis and mean pore throat size from centrifugal water drainage experiments (Soo, 1983) of the sandpack are 107 pm and 29.5 pm, respectively; sandpack initial porosity, e, , is 0.34. Both transient pressure drop and effluent particle concentration and size distribution are monitored. Y (Chevron 410H) and carbon tetrachloride, giving a mixture density of "-' A u ' 0
The oil drops consist of a neutrally buoyant mixture of mineral oil 1.00 f 0.02 g/cm3 and a viscosity of 1.5 mPa-s. Emulsions are produced in H. SO0 and C. J. RADKE 0 .
