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...
متن کاملA laboratory investigation on the potential of computational intelligence approaches to estimate the discharge coefficient of piano key weir
The piano key weir (PKW) is a type of nonlinear control structure that can be used to increase unit discharge over linear overflow weir geometries, particularly when the weir footprint area is restricted To predict the outflow passing over a piano key weir, the discharge coefficient in the general equation of weir needs to be known. This paper presents the results of laboratory model testing of...
متن کاملِِDischarge Coefficient in Oblique Side Weirs
Side weirs are flow diversion devices that are widely used in irrigation, drainage and urban sewage systems. The present study focuses on the investigation of the effect of oblique side weirs on the discharge coefficient of a side weir under subcritical flow condition in rectangular channels. In this study 106 laboratory tests were conducted and the results were analyzed to find out the influen...
متن کاملExperimental 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...
