Abstract	The vortex shedding contains plenty of flow information of gas-liquid two-phase flow, and the research on vortex shedding characteristic is closely related to anti-vibration design and measurement of two-phase flow systems. This paper studies the vortex shedding characteristic under bubble flow, slug flow and plug flow patterns by analysis of collected experiment signal with water and air as medium. It can conclude that when air volume fraction is not more than 15%, the repeatability is good and measurement error is within 10%, and the stable vortex shedding in the flow field could be observed. The method of flow pattern analysis based on the FFT can explain that flow pattern change is the main reason which leads to this phenomenon. And the presence of gas phase has really an influence on vortex shedding.
