Abstract
Multiphase flows are present in many industrial processes, its understanding is essential to improve such processes. As mature oil fields are being developed the amount of water produced together with the oil increases and so increases the interest in understanding liquid-liquid flows. Going straight this reality, the equipment’s dimension is intrinsically connected to multiphase flows characteristics correct being predicted, so allowing maximizing the productivities and reducing the operational costs. Within the horizontal liquid-liquid flow patterns, the dispersed flow patterns are of interest as they can be observed in several locations of the production line, such as valves, pumps and others. So, the correct prediction of dispersion characteristics such as apparent viscosity is necessary. This study proposes a theoretical work on comparison of experimental data for viscous oil-water flows from literature and models for apparent viscosity. This will be performed in two ways, comparing data of pressure gradient obtained in laboratories with the theoretical calculations as a function of the mixture friction factor and the apparent viscosity models.
