Description

technical field [0001] The invention relates to a measurement system for measuring phase holdup and phase interface in multiphase pipe flow, in particular to a conductivity probe measurement system for real-time measurement of phase holdup and phase interface in multiphase pipe flow. Background technique [0002] Gas-liquid, liquid-liquid, oil-gas-water multiphase pipe flow widely exists in energy, power and petroleum, chemical and other industrial fields. The multiphase flow in the pipe presents different flow patterns with the change of the flow rate of each phase. The cross-sectional phase holdup that changes in real time is one of the most basic and important characteristic parameters in the multiphase pipe flow of various flow patterns. Continuous phase interface structure exists in multiphase flow, annular flow and slug flow, and the phase interface structure has a significant impact on the heat transfer, mass transfer and resistance characteristics of multiphase pipe ...
