新型热扩散式测量技术助力气液多相流监测
Novel thermal diffusion measurement technique for enhanced monitoring of gas-liquid multiphase flows
摘要
Abstract
Gas-liquid multiphase flow frequently occurs in many industrial fields such as petroleum,chemical,power,metallurgy,and the online identification of its flow pattern and non-separation measurement of its flowrate are of great scientific and engineering significance.Since the thermophysical properties of gas phase and liquid phase are different,the change of the components of gas-liquid multiphase flow will cause the corresponding temperature response of the pipe wall heated by constant heat flow.Based on this phenomenon,our team proposed a thermal-diffusion measurement method to indirectly invert the flow pattern and the phase flowrates of the gas-liquid multiphase by the fluctuation of the temperature of the pipe wall,and the method was completely verified in the laboratory.This new method had the advantages of non-contact,radiation-free,low cost,real-time online,and no applied resistance,which helped the online monitoring and intelligent transformation of gas-liquid multiphase flow in industrial processes.关键词
