Dissipation of Turbulence in the Wake of a Wind Turbine [PDF]

Boundary-Layer Meteorology, 2014
The wake of a wind turbine is characterized by increased turbulence and decreased wind speed. Turbines are generally deployed in large groups in wind farms, and so the behaviour of an individual wake as it merges with other wakes and propagates downwind is critical in assessing wind-farm power production.

Green Developmentalism? The Political Economy of Hydropower in India in the 21st Century

Development and Change, EarlyView.
ABSTRACT This article critically examines the political economy of hydropower in India since its global reconfiguration as ‘green energy’ in the early 2000s. While an opportune convergence of interests among key global, national and subnational stakeholders contributed to the greening of hydropower in India, this reframing did not produce the expected ...

Quantifying Fiber Bridging in Mode I Fatigue Delamination of CFRP/GFRP Hybrid Laminates Using a Superposed Traction–Separation Model

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Hybrid CFRP/GFRP laminates offer an attractive balance between mechanical performance, damage tolerance, and cost efficiency. However, fiber bridging during mode I delamination increases crack‐growth resistance while masking the intrinsic fatigue behavior of the material. This study applies a traction–separation‐based superposition approach to

Differences in cluster and internal wake effects from mesoscale and large-eddy simulations off the US East Coast [PDF]

Wind Energy Science
Mesoscale simulations are increasingly used to estimate wake effects within and between large wind farms, despite limited validation for large-scale wake effects. This study evaluates the capabilities and limitations of mesoscale simulations in capturing

Wake Statistics of Different-Scale Wind Turbines under Turbulent Boundary Layer Inflow

Energies, 2020
Subscale wind turbines can be installed in the field for the development of wind technologies, for which the blade aerodynamics can be designed in a way similar to that of a full-scale wind turbine. However, it is not clear whether the wake of a subscale

Mergers and Acquisitions as Navigators of Climate Policy Shocks: Evidence from the NOx Budget Trading Program

Financial Management, EarlyView.
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 ...

Analysis of turbulence and vortex structures by flow mapping [PDF]

, 1997
The technique of Particle Image Velocimetry (PIV) flow mapping is reviewed and comparisons made with Laser Doppler Anemometry (LDA). Results are presented showing the application of PlV to the determination of coherent structures in grid-generated ...

Environmental Justice in the Brazilian Coastal Food Systems: Policies, Institutions, and Knowledges on Small‐Scale Fishers and Energy Development

World Food Policy, Volume 12, Issue 2, November 2026.
ABSTRACT This study explores environmental justice issues in coastal food systems, focusing on conflicts between small‐scale fisheries and the energy sector due to differing goals in managing food and energy sources. It does so by examining the interdependence between institutions, policies, and different types of knowledge; key elements in building ...

Estimating Wind‐Power Capacity Time Series From Production Data Using a Power Curve Model and Quadratic Optimization

Wind Energy, Volume 29, Issue 8, August 2026.
ABSTRACT Accurate, time‐resolved installed capacity data are crucial for forecasting and analysing wind‐power production. The time series of installed capacity is often only approximately known in regions with rapid wind power development. Public wind power databases may only be updated yearly and installation dates may not be differentiated within ...
