A Study of Local Drag Characteristics in Elbow Pipe

Abstract:

Many empirical formulas and diagrams have been employed to determine resistance coefficient of elbow/bend pipes. However, a big discrepancy of calculation results obtained from these formulas/diagrams exists. So it is difficult for users to choose an appropriate formula to calculate resistance coefficient of an elbow/bend pipe. In this paper, a comparison of several common formulas was made. And variations of resistance coefficient with both bend angle and curvature radius were graphically shown for reference of selection. In addition, flow characteristics in elbow pipe were analyzed.
