“Two-phase liquid-liquid flows”
The simultaneous flow of two liquids in a pipe occurs in a large number of applications in the oiland process industries. In oil production water is often extracted together with oil, particularly from mature oilfields, and the multiphase mixture has to be transported over long distances. Depending on the fluid properties, pipe size and the flow rates of the phases, different patterns can appear, ranging from completely separated to dispersed flows. The type of flow pattern determines important parameters of the two-phase flow (pressure drop, heat and mass transfer coefficients) and has an effect on the design and operation of pipelines.
The seminar will present an overview of the work on liquid-liquid flows that is carried out in the Department of Chemical Engineering at UCL. The experimental facilities and the range of instrumentation used for the study of flow parameters of interest, such as phase distribution, phase velocities, and drop size, will be discussed. The experimental findings in stratified flows will then be compared against model predictions on pressure drop and the transition boundary between separated and dispersed flows. A phenomenon of particular interest in dispersed flows is phase inversion. The findings from experimental investigations on the appearance of phase inversion and its effect on pressure drop will be compared against model predictions. Results will also be presented from dispersed flows in very small channels, used for intensified extraction applications.
