Experiment and Numerical Simulation on Hydraulic Loss and Flow Pattern of Low Hump Outlet Conduit with Different Inlet Water Rotation Speeds

Abstract: The rotation speed of water at the inlet of the low hump outlet conduit has a great effect on its hydraulic performance. Therefore, the influence of different inlet water rotation speeds on hydraulic loss and flow pattern of low hump outlet conduit is studied in this paper. By solving RANS equations and the RNG k-ε turbulence model, the hydraulic loss and 3D flow field of the low hump outlet conduit were calculated under different inlet water rotation speeds. To verify the numerical results, the model tests of… Show more

“…CFD (computational fluid dynamics) is a numerical simulation technique used to study fluid motion, heat transmission, and other phenomena by approximating complex flow field problems with a finite number of discrete points [1]. Numerous scientific phenomena are time-dependent, such as the development of thunderstorms, the combustion of substances, and the movement of ocean currents.…”
