The Effect of Installing Immerse Vanes on Scouring Around Bridge Abutments [PDF]
علوم و مهندسی آبیاری, 2019 To control scour, it is first necessary to examine the scouring mechanism and the flow patterns around the abutment. By constructing of the abutment, the approaching flow pattern around it is disturbed.

The influence of the submergence ratio of submerged vanes on the slope of the hole around the pier groups in a sharp bend [PDF]
Journal of Hydraulic StructuresBridges are metal or concrete structures, which make road connections across rivers when installed over river paths. When flooding or scouring occurs, several issues including bridge destruction and interruption of road connections arise.

Design of a high-specific speed turbine with non-uniform blade cascade [PDF]
EPJ Web of Conferences, 2019 This paper presents the hydraulic design of Kaplan type turbine in fully axial configuration. The turbine model consists of a straight pipe intake, a rib which covers the shaft, five axial guide vanes, a six blade runner and a 10,6°-full angle draft tube.

Numerical Investigation on the Effect of Asymmetry of Flow Velocity on the Wake Vortex of Hydrofoils
Journal of Marine Science and Engineering, 2022 The Karman vortex street is a common flow phenomenon. In hydraulic machinery, it is usually located downstream of the guide vanes and the runner blades, which reduces hydraulic performance and may also cause fatigue damage to the structure.

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract Near‐seafloor marine sediments on active margins have been shown to be stronger than those on passive margins. However, the reasons for this are not fully understood. To investigate the role of intrinsic properties, we performed resedimentation and oedometer tests and measured undrained shear strength, grain size, mineralogy, and plasticity on
