Analysis of the development of dynamic stall based on oscillating airfoil experiments [PDF]

open access: yes
The effects of dynamic stall on airfoils oscillating in pitch were investigated by experimentally determining the viscous and inviscid characteristics of the airflow on the NACA 0012 airfoil and on several leading-edge modifications.

The influence of blade curvature and helical blade twist on the performance of a vertical-axis wind turbine [PDF]

open access: yes, 2010
Accurate aerodynamic modeling of vertical-axis wind turbines poses a significant challenge, but is essential if the performance of such turbines is to be predicted reliably.

Rebound Effects in Circular Manufacturing: Overview of Potential Rebound Mechanisms Activated by Circular Strategies Across Key Business Processes

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular economy (CE) is increasingly adopted by the manufacturing industry to decouple economic growth from environmental impacts by optimizing resource use and minimizing waste generation. Nevertheless, circular manufacturing often triggers systemic responses that diminish or offset their potential environmental gains, resulting in the so ...

Numerical Investigation for the Impact of Single Groove on the Stall Margin Improvement and the Unsteadiness of Tip Leakage Flow in a Counter-Rotating Axial Flow Compressor

open access: yesEnergies, 2017
A low-speed counter-rotating axial flow compressor (CRAC) with single circumferential grooved casing treatment (CT) was investigated numerically. Both steady and time-accurate numerical calculations were performed to study the effects of the single ...

Translating Circularity Into Strategy: A Governance Meta‐Capability Framework

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Firms struggle to transition to circular economy (CE) models, often citing external barriers. Yet some firms succeed, whereas others fail: Why? We argue that success depends on a specific governance capability—a meta‐capability that allows firms to (1) sense and strategically reframe CE imperatives, (2) seize opportunities by aligning diverse ...

'Do it Yourself' Girl Revolution: LadyFest, Performance and Fanzine Culture [PDF]

open access: yes, 2009
Riot grrrl began as an independent music and political movement in the early 1990s emerging initially in the USA and few years later in the UK. From the beginning riot grrrl embraced a 'do-it-yourself' ethos operating outside the mainstream music ...

Shared Waters, Shared Responsibility: Solving Collective Action Problems in an Upstream‐Downstream Setting

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT The governance of shared water systems requires collaboration across diverse stakeholders. In this study we advance the theoretical understanding of asymmetric collective action problems (CAPs) by reassessing the role of third‐party interventions and emphasizing the strategic importance of policy brokers and institutional venues.

Study of Convective Flow Effects in Endwall Casing Treatments in Transonic Compressor Rotors [PDF]

open access: yes, 2012
The unsteady convective flow effects in a transonic compressor rotor with a circumferential-groove casing treatment are investigated in this paper. Experimental results show that the circumferential-groove casing treatment increases the compressor stall ...

Relationship between frequencies of pressure oscillations and rotor speed under rotating stall [PDF]

open access: yes, 2002
The correlation between the frequencies of pressure oscillation ωosc and the rotor speed (frequencies of rotor rotation ωRR) under established rotating stall were determined by three methods: directly from the time diagram of the oscillation process ...

Appraising Policies Through Social Multi‐Criteria Evaluation: Lessons From a Systematic Review of Applications

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT In response to renewed interest in analytical tools that address complex policy problems and move beyond linear‐rational approaches in policy appraisal, Social Multi‐Criteria Evaluation (SMCE) integrates participatory approaches with multi‐criteria analysis (MCA), thereby incorporating specialised knowledge and diverse social values and ...
