It is found that the bypass-pipe method can eliminate severe slugging completely. Using the bypass-pipe method , the range with severe slugging , especially the SS 1 , becomes smaller. The SS 1 and ss n are separated by stable flow. Superficial velocity of liquid has little influence on the elimination effect of bypass翩pipe method at a fixed superficial velocity of gas. Bypass-pipe method can decrease the pressure fluctuation of severe slugging and move the maximum amplitude from the boundary between SS 1 and SS nto SS n .A
