N2 - An experimental study of gas liquid flow in an inclined circular pipe was performed. Experiments were performed for two values of superficial liquid velocities and different gas flow rates. The angle of pipe inclination varies from 10° to 80° with respect to horizontal position. Wall shear stress was measured in the apex point of the pipe using an electrodiffusional technique. A strong effect of pipe inclination on wall shear stress was shown. The highest values of wall shear stress corresponded to the angles of 40° to 60°. A significant increase of wall shear stress at low gas flow rates was detected.
