Discharge formula for rectangular sharp-crested weirs
Aydın, İsmail; Altan Sakarya, Ayşe Burcu (2011-04-01)
Sharp-crested rectangular weirs used for discharge measurement in channels and laboratories are experimentally investigated. Height and width of weir plate are the two parameters characterizing the head-discharge relationship. Laboratory experiments are conducted by measuring the discharge and the head over the weir for variable weir heights and widths. Applicability of various formulations for the discharge coefficient are investigated. Experiments indicate that discharge is independent of weir height, whe...
Discharge prediction in flow measurement flumes with different downstream transition slopes
Göğüş, Mustafa; Atalay, Ahmet E.; Khatib, Jumana I. (2016-03-01)
Experimental testing of 9 different rectangular compound cross-section flow measurement flumes with different downstream slopes was conducted to yield the coefficient of discharge and the approach velocity coefficient. The aim of the experimental research was the determination of stage-discharge relationship in compound cross-section flow measurement flumes with different downstream slopes. One empirical predictive model for each of the coefficient of discharge and the approach velocity coefficient for the ...
Flow measurement in open channels by combined use of free surface PİV and CFD
Gharahjeh, Siamak; Aydın, İsmail; Department of Civil Engineering (2016)
Stream discharge measurement in open channels is of great importance in hydraulic engineering. For many years, classical devices such as propellers, current meters and weirs have been used for this purpose. In recent times, non-intrusive methods such as PIV (Particle Image Velocimetry) and PTV (Particle Tracking Velocimetry) have been very popular as they are more practical and convenient to automatically collect water free surface velocity which is further analyzed for discharge measurement. Image processi...
Flow rate-controlled pipetting for microfluidics: second-generation flexible hydraulic reservoir (FHRv2)

A critical component of microfluidic technology is the fluid pumping mechanism. Syringe and pressure pumps are typically used in the lab environment; however, their operations generate considerable dead volume that is often larger than the volume of the chip itself, leading to considerable waste of precious sample. As an alternative, pipetting allows for precise liquid dispensing with zero dead volume; however, it has a limited flow control. Recently, we have introduced a low-cost sample loading interface w...
