Free‐Surface Flow Through Screen

Publication: Journal of Hydraulic Engineering
Volume 115, Issue 10

Abstract

A prediction model is developed for the headloss through a screen that is placed in an open channel. For a given approach‐flow condition, screen inclination, and screen characteristics (i.e., flow contraction and deflection caused by a screen), values of the headloss coefficient can be predicted by the model. The result shows that there is an optimal inclination angle to minimize the headloss. The predicted values of the headloss are found to be in good agreement with the measured values in the experiments.
