Discharge coefficients for broad-crested weirs of low aspect ratios
… previously developed theoretical analysis of the discharge coefficient for broad-crested weirs is investigated. Experimentally determined discharge coefficients are presented for a broad-crested weir of small crest width in an attempt to verify the theory, and an investigation of the geometry of …

Enhancing Spillway Efficiency Discharge Coefficients: Insights from Historical Models and Case Studies of Ogee, Lateral, and Non-Linear Structures
Accurate estimation of spillway discharge capacity remains fundamental to dam safety and hydraulic design. Classical formulations such as those of USBR (1987), Ven Te Chow (1959), USACE (1990) and DWS Calibration Manual were developed under the idealised geometric and hydraulic assumptions. …

Estimating Flow Through Rock Weirs
… of knowledge exists relating to the stage-discharge relationship of these structures. Therefore, the goal of this research was to determine a weir equation and corresponding discharge coefficients that improve predictions of flow through rock weirs. A flume study was conducted to develop a …

Computer aided mathematical modelling of turbulent flow for orifice metering
… of output quantities of interest such as discharge and pressure loss coefficients. The model vas tested for convergence and general adequacy on an orifice of diameter ratio β= .7 in a 4 inch pipe line and at a Reynolds number of 105. Quantitative tests were then conducted on thin orifice …

A study of tip-leakage flow through orifice investigations
… greater than 10*. Measurements were made of the discharge coefficient as a function of back pressure ratio for a sharp-edged orifice and long orifices with an l/d from 1/2 to 8. The discharge coefficient measurements indicate the mass flow rate in an orifice with an l/d of approximately 2 is the …

Experimental and Numerical Study of Endwall Film Cooling
… The passing wakes increased the heat transfer coefficients at both the wake passing frequencies that were experimented. Due to the increasing film cooling jet turbulence and strong jet-mainstream interaction at higher blowing ratios, the heat transfer coefficients were amplified. A combination …

Inviscid flow from a slot into a cross stream
… and D. For a vertical slot, mass flow rates and discharge coefficients obtained from experiments and viscous numerical predictions are compared to present inviscid calculations. The results show good agreement at reasonable Reynolds numbers provided that the separation region is not large. The …

Experiments and simulation of shaped film cooling holes fed by crossflow with rib turbulators
… for select cases. The film cooling hole discharge coefficients and channel friction factors were measured for both rib configurations. Spatially-averaged film cooling effectiveness behaves similarly to holes fed by a smooth internal crossflow channel, but hole-to-hole variation due to the …

Modeling buoyancy-driven airflow in ventilation shafts
… for in AFNs using empirical relationships for discharge coefficients. This approach maintains the current structure of AFNs while enhancing their ability to simulate airflow through ventilation shafts. These improvements are shown to account for the "ejector effect" and predict airflow rates …

Qualitative Methods Used to Develop and Characterize the Circulation Control System on Cal Poly's AMELIA
… streamline, under the influence of a changing discharge coefficient as investigated along with the discharge coefficients effect on the extended flowfield. Collectively, the images depict the massive augmentation of the flowfield caused by the presence of the circulation control wing.</p>
