Numerical Simulation Analysis of Different Flow Directions in T-Junction
During the process of using the pipe, the leakage of the pipe perforation was caused by the erosion and wear of the micro solid particles in the pipe medium.Thus, DPM erosion prediction model in Fluent software was used to conduct numerical simulation of erosion, stress and shape variables in differ...

| description | During the process of using the pipe, the leakage of the pipe perforation was caused by the erosion and wear of the micro solid particles in the pipe medium.Thus, DPM erosion prediction model in Fluent software was used to conduct numerical simulation of erosion, stress and shape variables in different flow directions, and the areas where erosion wear was relatively serious, maximum stress and deformation occurred were obtained.Results showed that through the analysis, the erosion wear, stress concentration area and deformation parts were easy to occur during the process of using the tee pipe, so there were high requirements for the mechanical properties of the T-junction material.Under the shunt A condition, the erosion rate is 5.59×10-9 kg/(m2·s), and the maximum erosion wear was suffered.Under confluence B condition, the erosion rate was 3.03×10-9 kg/(m2·s), and the minimum erosion wear was suffered.Besides, the maximum stress and shape variables were also larger under the condition of larger erosion wear rate. |
