This paper presents two phase air-oil flow in pipe bend with tube inside diameter D = 0.016 m, curvature radius R = 0.11 in and angle 0 = 180[degrees]. The mixture of gas-liquid flowed upwards and downwards across the bend. In the paper upflow and downflow in pipe bend are compared. As a result, flow patterns formed in pipe bend are determined as well as determined void fractions of gas phase.
