Study on Velocity Distribution on Cross-Section Flow of T-Shunt.

T-shunt is one of the commonly used components in gas-liquid two-phase flow pipeline. It has the function of separating, transmitting and carrying fluid. The junction of the T-shunt is the area of diversion and confluence in the pipeline. In this paper, we study the characteristics of the T-shunt in the cross-section of the fluid flow. A visual window is installed at the end of the experimental T-shunt section, and the fluorescence pipe's cross-section image captured through the visual window is illuminated by the laser above the pipe. The fluid velocity field is calculated using the PIV (Particle Image Velocimetry) method and the velocity field is classified and analyzed. The result shows that there are great differences in fluid flow patterns on the cross-sections of the T-shunt at different positions, and great differences in the fluid erosion and corrosion of the pipe wall at different positions away from the T-shunt outlet.
