Comparison 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 کاملHydraulic Flow through a Channel Contraction: Multiple Steady States
Fig. 3. Plus signs: smooth flows (ii); squares: upstream moving shocks (iii); diamonds: steady shocks (iii); circles: oblique waves (i). Solid stars: flows with three possible states for different configurations and paddle lengths. Indicative error bars. • Three multiple steady states in regions (i/iii/iv): Fig. 4. Multiple states: F0 = 3.07 & Bc = 0.7. Left to right: upstream steady shock (iii...
متن کاملHydraulic Flow through a Contraction: Multiple Steady States
We consider shallow water flows through a channel with a contraction by experimental and theoretical means. The horizontal channel consists of a sluice gate and an upstream channel of constant width b0 ending in a linear contraction of minimum width bc. Experimentally, we observe upstream steady and moving bores/shocks, and oblique waves in the contraction, as single and multiple steady states,...
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 کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
