CFD and dimensionless parameter analysis of Froude number to determine the flow regime over ogee spillways
In this research, the numerical method of computational fluid dynamics and dimensionless parameter of Froude number have been applied to determine the flow regime over ogee spillways.Froude number is a dimensionless dynamic parameter calculated using the square root of the ratio of inertia force and gravitational force. Considering that the study of the regimes of flow over hydraulic structures...
متن کاملNumerical simulation of free flow over Gabion crump weirs
Environmentally friendly nature and the direct impact of gabion weirs on the quality parameters of rivers as well as simple design and construction of such structures, has putted them under consideration in the recent years. In this research, Hydraulic parameters of gabion crump weirs including water surface profile, discharge coefficient and through flow discharge are investigated numerically ...
متن کاملCFD SIMULATION OF FLOW OVER CONTRACTED COMPOUND ARCHED RECTANGULAR SHARP CRESTED WEIRS
Measurement of discharge in open channels is one of the main concerns in hydraulic engineering. The structures used for this aim should be accurate, economical and easy to use. Weirs are among the oldest and most convenient hydraulic structures that have been used in both laboratory and field for flow measurement in open channels. Due to limitations of simple sharp crested weirs, recently compo...
