Flow Regulation Characteristics of Active Flow-Regulating Vanes in U-Shaped Bends [PDF]
长江科学院院报[Objective] To address the issue that conventional river regulation structures struggle to dynamically adapt to the highly variable characteristics of natural rivers, this study develops an innovative active flow-regulating vane system.

Energy Science &Engineering, Volume 14, Issue 3, Page 1241-1257, March 2026.To investigate the influence of discharge valve opening on the self‐priming characteristics of a self‐priming pump, numerical calculations are conducted for four different discharge valve openings based on a circulation piping system. The hydraulic performance and the internal flow characteristics during self‐priming process are obtained.

International Journal of Mechanical System Dynamics, Volume 6, Issue 1, Page 3-21, March 2026.ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...

Submerged vane-attached to the abutment as scour countermeasure
Ain Shams Engineering Journal, 2015 Over the past few decades, the cause of many bridge failures has been reported to be abutment scour. A large number of studies have been conducted to develop countermeasures to ensure the safety of existing bridges. A submerged vane is a measure that has

Energy Science &Engineering, Volume 14, Issue 2, Page 764-779, February 2026.Based on entropy theory, this study presents a comparative numerical analysis of the flow energy dissipation (FED) in a VTSP under two distinct operating conditions: pump condition and turbine condition, both characterized by relatively high hydraulic efficiencies of 88.9% and 87.4%, respectively. In pump condition, the highest FED production occurs in

Effects of temporal and spatial variability in energy fluxes on phytoplankton
Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract Climate change has significantly altered the energy dynamics of lakes; however, little is known of how the temporal and spatial variation in energy fluxes impacts the structure and function of lake ecosystems. This study combined long‐term (2011–2018) measurements of lake energy fluxes with environmental, nutrient, and phytoplankton data at ...

Experimental Study of Submerged Vanes in Intakes under Sediment Feeding Conditions
E3S Web of Conferences, 2018 Sediment is transported along the river flow and deposited in the mouth of the intake structure over time and reducing the water intake capacity. Nowadays, many water intake structures lose their function and are closed to operation.
