摘要：Abstract Poor design of intake structures surrounding the hydraulic pump causes undesirable flow problems. These flow problems are in the form of severe vortices, and/or uneven flow distribution at pump intake. There are several methods in the literature to suppress such vortices but such methods might have an adverse impact on the operation and maintenance of the intake structure. In this paper, a new approach was investigated to reduce the vortex activity without any adverse impacts on the operation process. This approach depends on installing baffle posts on the top of the upstream side and the offshore long side of the sedimentation basin of the intake structure. An existing physical model of undistorted scale 1:38 was utilized to reduce the vortex activity using baffle posts. The model shows that baffle posts are effective in eliminating the vortex activity and hence improving the approach flow at the intake structure.
