Abstract
This paper presents an experimental vector velocity field for liquid phase during smooth stratified flows in horizontal channel with internal diameter of 44.6 mm and the shear stress profile. Experiments for determination of velocity profiles of liquid phase flow were performed for air-water flow. The experiments comprise superficial gas and liquid velocities between 0,0747 and 0,1067 m/s, and 0,0769 and 0,1321 m/s, respectively. The velocity profiles were determined in the central plane of test section with the non-intrusive technique Particle Image Velocimetry – PIV.
