Numerical Simulation and Computational Analysis of Pressure Drop of 90° Elbow with Large Pipe Diameter
In this paper,the flow resistance loss of large pipe diameter 90° elbow was numerically studied,the internal flow field characteristics of air flowing through the elbow were analyzed,and the influencing factors of flow resistance loss of fluid flowing through a 90° elbow were studied.Then,different formulas used to calculate the resistance coefficient of elbow were selected,and the reliability of equivalent length method and drag coefficient method for calculating the flow resistance loss of elbow was compared,which provides reference for designers.
