چکیده
Numerous natural and artificial streams, including those for irrigation ditches, wastewater treatment facilities, conveyance structures fish movement, have open channel confluences. The flow dynamics at around the junction are intricate; in particular, immediately downstream of junction, creates a zone separation on inner wall along with secondary recirculation patterns. structure this complicated depends several factors, rates both channels, angle confluence, geometry longitudinal slope bed discordance, roughness boundary, intensity turbulence. It also has significant impact erosion, bank scouring, etc. objective current work is to calculate velocity profile dimensions four angles (30o, 45o, 60o, 75o) through simulation process, best using three-dimensional model. This gives detailed application numerical solution (Finite Volume) via Flow 3D software. Results two discharge ratios, q*=0.250 q*=0.750 were shown; model experimental results agreed well. findings consistent past research demonstrate how main pattern affected by changes crossing angle, as well greater zones produced when ratio q* (main divided total flow) smaller. Analysis revealed that zone's smallest diameter will be 75ocrossing angle. Doi: 10.28991/CEJ-2023-09-05-07 Full Text: PDF

Open channel junction is one of the most common hydraulic structures that are used in various practical situations such as sewer, drainage, and flood control systems. Knowing the fluid flow behavior, is one of the most important topics in designing the efficient open channel junctions. The complexity and deviation of flow in the junction’s zone disrupts the proper functioning of the flowmeter d...
متن کاملNumerical Investigation of Network Models for Isothermal Junction Flow
This paper deals with the issue of how to properly model fluid flow in pipe junctions. In particular we investigate the numerical results from three alternative network models, all three based on the isothermal Euler equations. Using two different test cases, we focus on the physical validity of simulation results from each of the models. Unphysical solutions are characterised by the presence o...
