Design and Modification of Side Intake Using Numerical Simulation
Abstract
Side intakes have been proposed to divert flow to headrace tunnels from a reservoir. Three side intakes have been provided to pass the design discharge of 536 m3/s during the dry season and a maximum discharge of 551.37 m3/s during the wet season. The simulations are performed to find the velocity contour, pressure contours, velocity vectors, and vorticity at characteristic horizontal and vertical planes using ANSYS Fluent. The head loss is then evaluated and compared with the calculation from the empirical formula. The geometry of intake with response to the reservoir influences the symmetric flow through each opening of intake. A comparison has been made for the modified geometry concerning the original geometry, which has better hydraulic performance and less head loss.
