摘要
准确识别相界面结构形态是相界面力学分析的基础,也是研究气液两相流动规律的一种重要技术手段。针对动力、能源、化工、医药及航空等领域气液两相管流的相界面拓扑性强、变化速度快、实现准确测量难度大等特点,开展了气液两相管流相界面检测技术和数值模拟方法的综述研究。相界面检测技术主要有电容法、电导法、光导法、射线法、热学法、声学法、核磁共振法以及近年来发展起来的金属丝网传感器检测技术、过程层析成像技术和高速粒子成像技术;数值模拟方法有PIC法、MAC法、ALE法、VOF法和Level-Set法等。通过对比分析各种方法的优势和局限性,提出了气液相界面的追踪检测技术的研究策略和发展趋势,可为气液两相流的研究提供有益参考。
The accuracy detection of the interface is not only the basis of the mechanics analysis,but also a powerful measure for the investigation of two-phase flow.Gas-liquid occurs widely in the energy,power,chemical engineering,petroleum and aviation,and there is an obvious topological and transient interface which is difficult to be detected accurately.The paper has summarized the interface detection technology and numerical simulation method.The decetion technology includes capacitance,conductivity,optical,ray,heatacoustic,nuclear magnetic resonance;the WMS,PT and PIV technologies are developed in recent years which enhance the precision of the interface detection;the numerical simulation includes PIC,MAC,ALE,VOF,Level Set,and so on.The methods are compared and analyzed with the advantages and boundedness,and some strategy and tendency are proposed,which may provide some references for the two-phase flow investigation.
