I have a broad interest in fluid mechanics and aerodynamics with a strong emphasis on experimental testing in large, low-speed wind tunnels. University of Glasgow has been home to the former Handley-Page and deHavilland industrial sized wind tunnels for several decades, and I am the local co-Investigator with responsibility for the deHavilland wind tunnel as part of the UK National Wind Tunnel Facility project.
The wind tunnels are suitable for academic and industrial research, and, in my role as wind tunnel director for Aerospace Sciences and the James Watt School of Engineering atthe University of Glasgow, I am the primary contact point for advice for and access to these facilities.
I obtained a First Class Honours Bachelor Degree in Aeronautics (Finsbury Medal winner) from Imperial College, London, and a PhD in experimental fluid mechanics from University of Manchester. After this I joined the Department of Aerospace Engineering at University of Glasgow in 1989 as a research assistant to participate in wind tunnel tests of dynamic stall in the Handley-Page wind tunnel. At the time Glasgow was forging a reputation as a leading centre for experimental unsteady aerodynamics under the guidance of Professor Roderick Galbraith, and much of the work was geared towards unsteady aerodynamic phenomena of rotor flows and rotor wakes.
I subsequently helped develop much useful collaboration with other UK universities and industrial organisations, and I have participated in testing projects in the USA and continental Europe.
Research projects for which I provided significant input include:
- dynamic stall, unsteady separation and unsteady reattachment of aerodynamic flows (EPSRC, DARP, AFOSR, US Army)
- blade-vortex interaction (EPSRC, US Army)
- Vortex Ring State (including visiting professor to Professor Ömer Savas at UC Berkeley, California, with NASA Ames)
- rotor wakes in ground effect (GARTEUR AG17 and AG22)
- andrology (MRC funded, Scottish Enterprise)
- aerodynamic drag reduction (EU funded, ARA and VZLU (Prague))
- propeller aerodynamics (EPSRC, Aircraft Research Association and Dowty)
- rear empennage aerodynamics (EU funded)
- UK National Wind Tunnel Facility (EPSRC, ATI)
- Vertical Lift Network (EPSRC)
Expertise with experimental instrumentation includes development of a Particle Image Velocimetry system at Glasgow, a technique in which I am a highly experienced, and other experimental methods that I use are for unsteady surface and wake pressure measurement, Laser Doppler Anemometry, force and moment measurement, and flow visualisation among others.
My research work is presented in the relevant journals including Journal of Fluid Mechanics, Experiments in Fluids, AIAA Journals, Aeronautical Journal, Physics of Fluids, Aerospace Science and Technology, and I review articles for these journals.
Industrial customers who I have completed wind tunnel testing projects on behalf of include the wind energy and renewables sector, manufacturing, road vehicles, and example projects are as follows:
- wind loading on building installations and infrastructure
- 2-D aerofoil characterisation
- propulsion concepts
- dynamic stall
- road vehicle aerodynamics
