Flow Modeling in the Wake of a Francis Turbine with Hydraulic Charge: Case of Songloulou-Cameroon [PDF]
Journal of Applied Fluid MechanicsCavitation in hydraulic installations is still a major concern when it comes to producing electricity. We are aware of the danger of cavitation and the damage it can cause.

Wildlife Biology, Volume 2026, Issue 5, September 2026.Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Conceptual Model of the Debarking Process of Large Wood in Rivers
Water Resources Research, Volume 62, Issue 9, September 2026.Abstract When transported in rivers by short‐term episodic events such as floods and debris flows, large wood interacts with the flow, sediment, and river boundaries, leading to physical degradation such as weathering, abrasion, and breakage. This degradation, manifested as mass loss and structural alteration, weakens wood stability, increases mobility,

Influence of 3D Guide Vanes on the Channel Vortices in the Runner of a Francis Turbine
Journal of Fluid Science and Technology, 2006 It is known that the pressure fluctuation in the runner will become large when a Francis turbine operates at the low flow rate and high head. One of the reasons is the occurrence of channel vortices, which are caused by the three-dimensional flow ...

Financial Management, Volume 55, Issue 3, Page 457-484, Fall 2026.ABSTRACT We examine how mergers and acquisitions (M&As) enable firms to adapt to climate policy shocks. Exploiting the adoption of the Nitrogen Oxides (NOx) Budget Trading Program (NBP) across US states as an exogenous shock, we find that firms with NOx‐emitting plants subject to the NBP are more likely to engage in M&As, particularly through vertical ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.Abstract Near‐surface wind regimes govern critical Earth system processes including dust mobilization, ocean mixing, and wildfire spread, yet their multi‐decadal evolution under anthropogenic forcing remains poorly constrained. Here we quantify extreme wind frequency changes (1981–2024) using ERA5‐Land reanalysis with a monthly aggregation approach ...
