高速摄像技术目前已经成为研究直管内多相流流动规律的常规手段之一,从多相流、油气集输以及微/小管道流动等三个方面,对基于高速摄像技术进行的多相流流动规律研究进行了归纳分析。总结了以高速摄像为研究手段的不同类型管道内多相流动的流动特性,阐明了针对不同流动体系中高速摄像技术的使用方法,同时指出了目前通过高速摄像研究多相流动所面临的困难。购买并搭建了高速相机测量系统,同时搭建了多功能油气集输实验装置,为进行螺旋流流动特性、管道携液以及气/液颗粒流动特性等相关实验做好准备,为基于高速摄像系统进行的多相流研究提供参考和借鉴。
High-speed camera imaging technology has become one of the common methods to study the flow pattern of multiphase flow in straight pipe. From three aspects of multiphase flow, oil gas transportation and micro/small pipe flow, the research of multiphase flow law based on high-speed camera imaging technology is analyzed. The flow characteristics of multiphase flow in different types of pipes with high speed imaging are summarized. The methods of using high speed imaging technology in different flow system are expounded, and also the difficulties in the study of multiphase flow through high-speed camera imaging are pointed out. A Flare high speed camera measurement system is bought and the multifunctional oil-gas gathering and transportation experiment device is set up. It makes good preparation for relevant experiments like the flow characteristics of spiral flow, the liquid carrying and the flow characteristics of gas/liquid particles. It provides reference for the research of multiphase flow based on the high-speed camera imaging system.
