Study of relative energy dissipation of trapezoidal and arced piano key weirs equipped with baffles

نویسندگان

چکیده

Abstract Energy dissipation is one of the important issues in piano key weirs (PKWs). Excessive energy at weir's toe can cause scouring. In previous studies, arced (APKWs) has not been investigated. this experimental study, effect weir height as well and arrangement baffles located on outlet slope amount dissipated were examined trapezoidal (TPKWs) APKWs. Experiments performed models with two to width a cycle ratios equal 0.9 1.2, three baffle 0.06, 0.12 0.18 A B-arrangements. The results showed that increase discharge, relative decreases. higher also larger baffles. Also, arrangements significant energy.

Experimental study of determining the discharge coefficient relationship of trapezoidal Piano Key Weirs and sensitivity of effective parameters in it

Piano Key Weirs, a developed scheme of labyrinth weirs. In this study, 36 trapezoidal Piano Key Weirs models were conducted in 360 different geometric and hydraulic conditions. Experiments were conducted in a 11 m long flume with a rectangular cross section of 49 cm width and 70 cm height in which the effect of dimensionless ratios on the discharge coefficient was investigated. The results show...

Numerical Analysis of Flow Hydraulic in Trapezoidal Labyrinths and Piano Key Weirs

The flow fields over a trapezoidal labyrinth weir (two-cycle) and a piano key weir were simulated using Flow3D, studying the impact of each model on the flow field in the weirs and the coefficient of discharge in comparison with the available experimental data. Moreover, the models were investigated experimentally in a 12.5 m long, 0.3 m wide, and 0.4 m high rectangular flume under clear-water ...

Experimental study on the effect of number of cycles on the hydraulics of trapezoidal piano key side weirs

Recently pianokey weirs become important in hydraulic structures. In this paper effect of the number of cycles on the flow of pianokey sideweir has been investigated experimentally. 45 experiments on single, two, four, six cycles pianokey and sharp crest linear weir on different heads (H/P = 0.3, 0.5, 0.65, 0.85 and 1) has been conducted. The input flow rate to the main channel was applied in s...

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

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 structu...

Comparing the Behavior Hydrodynamics Flow Over of Type A, B, and C Piano Key Weirs

The piano key weir (PKW) is a new type of hydraulic structure that has been of great interest to designers in recent years. In the present study, steady flow on the types A, B, and C PKWs was studied numerically using the FLOW-3D numerical model. Upon software validation using the experimental data, the 3D flow pattern on the types A, B, and C PKWs was studied, and along with the evaluation of ...
