Slug ?ow is the most prevalent problem of two-phase ?uid transportation in the petroleum industries. Here, large amplitude waves lead to the pipe blockage that possible to cause the damage of the mechanical structure. The experimental investigation of gas-liquid slug two-phase ?ow in a horizontal pipe was carried out to investigate the initiation and ?ow development mechanisms. Air and water were used as the working ?uids. The inner pipe diameter was 26mm. In the present experimental study, the slug initiation mechanisms were explained by visual observation and pressure ?uctuations. Moreover, the initiation frequency of slug ?ow and the evolution of passing slug frequency along the pipeline were also observed by using two high video cameras. As a result, several basic mechanisms of slug ?ow initiation in a horizontal pipe were clari?ed. Those were the wave coalescences, the wave growth mechanism, and the large disturbance waves. A ?ow initiationmap wasproposed to address those mechanisms. Here, theslug initiation frequency and thepassingslugfrequencywereobtainedinrelationtothepipelengthposition.Thestaticpressuremeasurement was also used to verify the image processing results on the characteristics of slug initiation mechanisms. The obtained qualitative and quantitative results from the investigation can be used to evaluate the recent available models.
