Numerical Optimization of a Stall Margin Enhancing Recirculation Channel for an Axial Compressor

Fluids, 2019
A proof of concept is provided by computational fluid dynamic simulations of a new recirculating type casing treatment. This treatment aims at extending the stable operating range of highly loaded axial compressors, so to improve the safety of sorties of

Translating Circularity Into Strategy: A Governance Meta‐Capability Framework

Business 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 ...

Aerodynamic Inner Workings of Circumferential Grooves in a Transonic Axial Compressor [PDF]

, 2007
The current paper reports on investigations of the fundamental flow mechanisms of circumferential grooves applied to a transonic axial compressor. Experimental results show that the compressor stall margin is significantly improved with the current set ...

The Minimum Age of Criminal Responsibility Internationally—History, Systems and the Future

Criminal Behaviour and Mental Health, EarlyView.
ABSTRACT Background In most countries, a criminal conviction requires evidence that the individual committed the act and that they had the mental capacity to understand what they were doing and that it was wrong. Youth, as an indicator of brain development, is one factor affecting criminal capacity.

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

Environmental 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.

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

Energies, 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 ...

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

, 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 ...

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

, 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

European 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 ...

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

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.
