Wind turbine performance improvements using active flow control techniques

S Shun, NA Ahmed - Procedia engineering, 2012 - Elsevier
The ability of a wind turbine to react to rapid fluctuations in wind velocity is blunted by the
massive rotational inertia of the rotor assembly as a whole, as well as the mass of individual …

Experimental study of a vertical jet in a vegetated crossflow

Airfoil separation control using multiple-orifice air-jet vortex generators

S Shun, NA Ahmed - Journal of Aircraft, 2011 - arc.aiaa.org
THE maximum normal force developed by a single element airfoil may be limited by flow
separation, which can occur at higher angles of attack. This phenomenon often results in a …

The effect of unsteady flow rate increase on in vitro mouth–throat deposition of inhaled boluses

B Grgic, AR Martin, WH Finlay - Journal of aerosol science, 2006 - Elsevier
A procedure for measuring the effects of flow increase rate (FIR) on mouth–throat and
