多相流是一种在自然界,工业中很典型的流动形态,普遍存在于石油的开采,石油的运输过程中。本次研究的是原油中含油水两相,其流量的测量,由于多相流的流动特性相对复杂,并且不同相流间存在着相对速度以及界面效应,导致参数检测的复杂程度和难度大。由于本人能力有限,为简单起见只考虑流体的流速和分相含率,忽略了其它复杂的参数,外界影响和气体的存在。
Multiphase flow is a typical flow pattern in nature and industry, commonly found in the exploitation of oil and the transportation of petroleum. In this study, the oil-water two-phase in crude oil is measured. Due to the relatively complex flow characteristics of multi-phase flow and the relative velocity and interface effect between different phase flows, the complexity and difficulty of parameter detection are large. Due to my limited ability, only the flow rate and phase separation of fluids are taken into consideration for simplicity, while other complicated parameters, external influences and gases are ignored.
