Abstract: 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, heat acoustic, 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.
