Abstract

The flow ductility at the threshold of entry into the overflow is affected by the geometric shape of the conduction wall, which, if designed properly, can reduce the discharge coefficient significantly. For this purpose, in the present study, a physical model of a stack overflow and three arched conductor walls were used with different angles to flow paths. The results obtained in this study showed that by increasing the upstream head for all three conduction walls, the width of the contraction section is reduced. Also, in a steady upward head, the average width of the shrinkage cross section in the guiding wall with the 60 degree angle was the highest. By increasing the head upstream, the coefficient of discharge decreased, while the variation of the discharge coefficient in relation to the flow rate for all three arc-conductor walls was a downward trend. Finally, it was found that in a constant head, the amount of flow through the overflow in each of the three conductive walls did not differ significantly.
