Experimental study of two phase flow pressure drop and flow pattern in horizontal and incline pipe

Flow pattern and pressure drop in horizontal and inclined pipe (from angles 0° to 40°) for air–water two-phase flow were experimentally studied. The test section, with an inside diameter 30 mm and 3 m length was made of plexy-glass to permit visual observations of the flow patterns. The horizontal flow phenomena, which are plug, slug, stratified, stratified/wavy, and inclined flow phenomena which are slug, plug, annular/slug, slug/wavy, slug/bubble and annular/bubble flow are observed. Four differential pressure transducers were installed to measure two phase flowpressure drop across the test section. The range of transducers is 0-100 psig. This diverse data not only can be used for developing general experimental correlation in wide range of flow patterns and angles but also they can use for validation of computer codes or simulation software results.
