Downstream hydraulic geometry of alluvial rivers
This article presents a three-level approach to the analysis of downstream hydraulic geometry. First, empirical concepts based on field observations of ‘poised’ conditions in irrigation canals are examined. Second, theoretical developments have been made possible by combining basic relationships for the description of flow and sediment transport in alluvial rivers. Third, a relatively new conce...
متن کاملHydraulic properties of the Hemopump HP31: a study of the downstream pressure distribution
The Hemopump was commercialized as an useful tool for the left ventricle assistance. Bioengineers and clinicians showed great interest to develop applications and to analyze its hydraulic behaviour; in this work an application for axial pump in different conditions is presented. A study of the spatial pressure distribution generated by the impeller of the Hemopump is investigated in highly accu...
متن کاملComparison of Experimental Study and Cfd Analysis of the Flow under a Sluice Gate
Flow in the open channels has great importance in the hydraulic engineering. Any disturbances as contractions and expansions affect the flow characteristics like velocities, flow rates and water surface profiles. Their effects on the flow must be considered during the design process of flow structures. In the last decades numerical solutions become popular as experimental studies take time, may...
متن کاملThe effect of disturbances on the flows under a sluice gate and past an inclined plate
Free surface potential flows past disturbances in a channel are considered. Three different types of disturbance are studied: (i) a submerged obstacle on the bottom of a channel; (ii) a pressure distribution on the free surface; and (iii) an obstruction in the free surface (e.g. a sluice gate or a flat plate). Surface tension is neglected, but gravity is included in the dynamic boundary conditi...
متن کاملFree-surface flow simulations for discharge-based operation of hydraulic structure gates
We combine non-hydrostatic flow simulations of the free surface with a discharge model based on elementary gate flow equations for decision support in operation of hydraulic structure gates. A water level-based gate control used in most of today’s general practice does not take into account the fact that gate operation scenarios producing similar total discharged volumes and similar water level...
