Webb20 nov. 2024 · Abstract. This paper presents CFD simulations of the flow through a real bottom outlet equipped with high-head slide gates. The operating head of the gates and the maximum flow rate are 70 m and 650 m3/s, respectively. The numerical simulations were performed in ANSYS-FLUENT version 19.2. VOF method was used to model the free … WebbThe gate is provided with a lifting mechanism so that the aperture beneath it may be set to any desired position. When closed, the aperture is sealed so that no flow can pass through the gate. In this experiment we measure the discharge under the gate and establish the effective coefficient of discharge. five star flex hybrid notebinder 1.5 inch
