Professor Richard George James Flay

BE(Hons), PhD (Mech Eng)

Biography

Professor Flay joined the Mechanical Engineering Department in 1984 as a senior lecturer, and he has been professor of Mechanical Engineering since 2000. His main teaching areas are fluid mechanics, thermodynamics, aerodynamics, design and wind engineering.

His research interests are focused on the wind, and he has consulted and researched in the areas of wind engineering, wind energy, wind tunnel design, wind tunnel testing. A highlight was his design of the world’s first wind tunnel capable of producing twisted flow for testing yacht sails. This wind tunnel was used by Team New Zealand, and helped them win the America’s Cup in 1995 and to successfully defend it in 2000. More recently he has advised on the design of wind tunnels in Hong Kong, Australia, India and New Zealand.

Professor Flay is Director of the Yacht Research Unit, which has a superb international reputation, and carried out a large proportion of the world’s wind tunnel testing of yacht sails. In 2014 the Yacht Research Unit moved to the University's Newmarket Campus, where it is co-located with the Aerodynamics Laboratory in the Wind Tunnel Hall, Building 901, Level 5. A closed circuit wind tunnel suitable for a wide range of aerodynamic investigations, with a test section 3.6 m wide and 2.5 m high was designed and built in-house, completed in June 2015. It has expanded the capability of the Yacht Research Unit and the Wind Engineering Group, and we are undertaking exciting research on wind excitation of buildings, roofs, and other structures and we have developed new instrumentation to measure the wind environment around buildings for human comfort information. A special sensitive balance in the new wind tunnel is available to measure the drag of cyclists and skiers, and we also carried out wind tunnel tests on the Cyclors on the Emirates Team New Zealand catamaran that won the America's Cup in 2017.

Professor Flay's current research interests include generating artificial buoyancy vortices for carbon neutral power generation, and studying New Zealand's increasing wind hazard from climate change.
