They are used to reduce sediment entrainment to water intakes structures. Thevane’s geometric parameters affect the flow pattern around the vanes. Numerical solution of the threedimensionalReynolds-Averaged Navier-Stokes equations for turbulent flows around submerged vanesplaced in front of the intake in curved channel with 180° bend using the Fluent software in order toidentify the optimum vane’s angle and height and the last vane position is the aim of this paper. Theresults of numerical model are compared with available experimental data.Investigations show that the optimum angle of attack for the first vane is 20° to approach flow and theoptimum ratio of the vane height to the flow depth is 36%. Also the last vane position just off thedownstream corner of the intake is recommended.}, keywords = {}, title_fa = {شبیه سازی عددی الگوی جریان در اطراف صفحات مستغرق در مقابل دهانه آبگیر در قوس 180 به منظور تعیین زاویه و ارتفاع بهینه صفحات}, abstract_fa = {}, keywords_fa = {}, url = {https://jhyd.iha.ir/article_85527.html}, eprint = {https://jhyd.iha.ir/article_85527_081be202a4c2ed1243ed8dbbe0edd8b1.pdf} }
