Original abstract

The experimental study of two-phased flow of immiscible liquids is presented in the paper. Two liquids were chosen for experiment – water and corn germ oil. Flow was observed in a horizontal pipeline. This type of flow is commonly found in wide variety of industrial applications. For example: in pipelines in subsea oil production systems. A special experimental circuit was built, where important factor was control of inlet velocities for both liquids. Thanks to that we were able to choose different types of flow regimes. Flow was observed in a long horizontal pipeline, where fluids mix at the entrance. With water coming straight to the pipeline and oil inlet being fed from above. Experimentally several flow regimes were observed, from which flow regime map is created. Second part of the paper introduces results from Particle image velocimetry (PIV). PIV is an optical measurement technique which allows to measure velocity vectors, without influencing the flow itself. This is done by use of tracing particles. For chosen liquids different type of particles has to be used. This led to main problem, where one PIV device cannot capture both types of particles. This study deals with this problem. As result several flow regimes are presented in dependence on the inlet velocities of liquids.
