Title

Comparison of Hydraulic Performance of Linear and Nonlinear Piano-Key Weirs in Plan

Pages

  395-407

Abstract

 In this research, by using FLOW3D, the performance of non-linear (arced) piano key (PKW-NL) in plan and Linear piano key Weir (PKW-L), with equal length of Weir, was compared. Results showed that nonlinearity of the Weir caused 20% increase in the Discharge coefficient. Investigating the velocity contours for these two Weir models also showed that maximum velocity within the PKW-NL Weir structure is about 30% lower than the PKW-L Weir. Also, the performance of non-Linear piano key Weir was evaluated under inward (PKW-IC) and outward (PKW-OC) curvatures to the channel. Results showed that in the case of PKW-IC Weir, the Discharge coefficient was increased by 8% as compared to the PKW-OC Weir. Investigating the pressure contours for these two Weir models also shows that the average pressure within the PKW-IC Weir structure is about 5% higher than the PKW-OC Weir. This increase in pressure leads to a decrease in the speed and better distribution of flow over the Weir keys.
