Study on the Influence of Internal Flow Field in Pipeline Elbow by the Guide Plate
The liquid-conveying elbow is an very important part in the piping system, in this paper, the internal flow field in the pipeline elbow is studied, its structure is optimized, and the guide characteristic is improved. The results show that the internal total pressure difference in the original elbow is 29506.27 Pa, the Max-velocity is 7.12 m/s, and the internal flow field is very uneven；The internal total pressure difference can be greatly reduced through setting up the guide plates appropriately, its internal total pressure difference decreases as the number of guide plates increases, the Max-velocity decreases first and then increases as the number increases; When the number is a constant, the optimal result of guide plate according to the gold ratio arrangement is superior to the equidistance ratio arrangement; When the export length of guide plate is 50 mm, the total pressure difference is 14942 Pa in the elbow, comparing it to the result of the original elbow, it decreases 49.26%, the optimal design has an very obvious effect.
