A swirl gas-liquid two-phase flow has been researched as basic studies for cyclone separators, a swirl gas-liquid-solid three-phase flow and so on. In the previous paper, using the vertical pipe of a 30mm I.D. and approximately 5m height, flow patterns were classified into four patterns using the mixing unit whose cone angle were 0, 4 and 12 degrees. Since the distance between experimental points was long, the boundary line between flow patterns was indistinct. In the present study, we aim to present the flow regime map more in detail. Using the mixing unit whose cone angle was 4 degrees, flow patterns were observed and swirl length was measured. Detailed flow regime map was presented, and the influence of volumetric fluxes of each phase on the swirl length was investigated. Experimental equations were presented to estimate the swirl length.
