Active Control of an Axial Flow Compressor via Pulsed Air Injection [PDF]

, 1996
This paper presents the use of pulsed air injection to control the onset of rotating stall in a low-speed, axial flow compressor. By measuring the unsteady pressures near the rotor face, a control algorithm determines the magnitude and phase of the

The Politics of Policy Robustness: A Central Paradox and Computational Review of Adaptive Policymaking

Public Administration and Development, EarlyView.
ABSTRACT Policy robustness, that is, the capacity of policies to sustain performance across diverse and uncertain futures, is increasingly considered a core objective of public policymaking. Although adaptive policymaking is widely promoted as an approach to achieving policy robustness, it suffers from a central paradox highlighted by theories of the ...

Influence of slotted casing treatment with surface roughness and dimples on the performance of an axial flow fan

Cogent Engineering
A numerical analysis is conducted to assess the impact of slotted casing treatments, dimples, and surface roughness on the performance of an axial flow fan. Five configurations were evaluated: baseline (without any flow control), axial slots, axial slots

How uneven access shapes the socio‐economic and environmental potential of game meat value chains: The case of legal game meat in Zambia

People and Nature, EarlyView.
Abstract Game meat contributes to human nutrition, food security and sociocultural practices around the world. Game meat also comes with risks, including overharvesting and zoonotic and food‐borne disease. These may be pronounced where game meat travels along complex value chains from rural to urban areas.

The impact of COVID‐19 on public perceptions of wild meat in Central Africa

People and Nature, EarlyView.
Abstract Wild meat is a significant source of food and income generation in Central Africa. However, there is little knowledge of how the assumed link between COVID‐19 and wild meat consumption has been discussed by the media and received by the public. In this study, we conducted media content analysis of 264 articles published in 2019–2020 related to

Study of Near-Stall Flow Behavior in a Modern Transonic Fan with Composite Sweep [PDF]

, 2011
Detailed flow behavior in a modern transonic fan with a composite sweep is investigated in this paper. Both unsteady Reynolds-averaged Navier-Stokes (URANS) and Large Eddy Simulation (LES) methods are applied to investigate the flow field over a wide ...

Some love them, others hate them: Understanding farmers' tree planting decisions in Scotland

People and Nature, EarlyView.
Abstract Agroforestry is increasingly recognized as a sustainable agricultural land use system with potential to sequester carbon, create and repair habitats, enhance biodiversity and offer environmental and socio‐economic benefits, including improved agricultural productivity.
