Experimental Study Of Oil-water Flow In A Horizontal Pipe And A Stirred Tank

Oil-water two-phase flow is playing a significant role in economy and safety of Surface Engineering and long-distance pipeline.In the development of two-phase flow,it is of no difficulty to find out substantial efforts for gas-liquid system.In contrast,researches for liquid-liquid two-phase flow have been published less quantitatively so far.The reason for that can be attributed to the complexity generated by liquids mixture carrying similar relatively physical properties.And the issue on flow behavior of multiphase pipeline has always become a key point for petroleum industry,and this is the case particularly with oil-water two-phase flow.In this paper,the flow behavior including flow patterns and pressure gradient is investigated in order to further understand the oil-water system.Firstly,designation of flow loop facility is conducted including calculation,CAD drawing,installation and commissioning.A separator is set up to ensure an effective separation between oil and water.Secondly,a high speed camera system is used to record flow patterns,and Particle Image Velocimetry(PIV)is utilized to measure velocity properties in the intermediate mixture velocity while in the high one droplet size distribution is tested by FBRM.Finally,turbulent properties of the oil-water two-phase flow in a stirred tank are measured using angle-resolved 2D-PIV which can be recognized as the basis of a deep understanding for the flow structure of pipe flow systems.
