The flow of oil-in-water macroemuisions through both porous media and capi!!ary tubes has been studiedexperimentally and described mathematically.Macroemulsions are those emulsions with most of their droplet diameters greater than 1 pm, which is the same order of magnitude as the pore constrictions. The emulsions were pumped with a positive displacement pump through several poroti media and capillary tubes connected in series. The rheo!ogical behavior of macroemulsions with oil concentrations ranging from 10 to 70 vok?bwas obtained using capillaty tube data. Emulsions with oil concentrations fess than 50% behaved like iVewtonianfluids, while those with concentration greater than 50% behaved like pseudoplastic jluids. ViscoeIastic effects were not observed for these jluiak. A correlation, which zmes both capilla~and core flow data, was developed for describing thejhw of non-Newtonian macroemu!sions through porous media. T'13led to a generid equation that reduced toDarcy's law for Newtonian fluids. The auerage -relati~eerror found when applying the method of correhrtion was * 4?4.
