Critical systems heuristics [PDF]
, 2010 Critical systems heuristics (CSH) is a framework for reflective professional practice organised around the central tool of boundary critique. This paper, written jointly by the original developer, Werner Ulrich, and Martin Reynolds, an experienced ...

Diverging flow in Y-junctions: laminar, transitional and turbulent
Magazine of Civil EngineeringThis investigation is aimed at determining flow regimes in Y-junctions with flow division. Air velocity and velocity pulsations are measured using a hot-wire anemometer in a wide range of Reynolds numbers Re = 400–6000.

Aerofoil behaviour at high angles of attack and at Reynolds numbers appropriate for small wind turbines [PDF]
, 2014 The aerodynamic characteristics of a NACA0018 aerofoil have been investigated experimentally for incidence angles ranging from 0° to 180° in closed-jet and open-jet wind tunnels with different blockage coefficients at Reynolds numbers from 60,000 to 140 ...

Experiments on a Flettner rotor at critical and supercritical Reynolds numbers
Journal of Wind Engineering and Industrial Aerodynamics, 2019 Abstract The Flettner rotor is attracting increasing attention as a viable technology for wind-assisted ship propulsion. Nonetheless, the influence of the Reynolds number on the aerodynamic performance of rotating cylinders is still unclear and under debate.
