Capillary bundle model for gravitational flow of emulsion through granular media and experimental validation

In this paper a numerical model, describing the process of gravitational flow of the emulsion through the porous structures, has been developed. Using this model, it was possible to predict the flow rate of fluid through the bed, and changes in the emulsion structure. This model was based on the concept of capillary bundles and assumed conversion of granular deposit into a network of capillaries. The calculation results obtained using the proposed model were compared with the results of own experimental works and high accordance was achieved.
