Wind tunnel testing is of crucial importance since it is hard to obtain the coefficients in the aerodynamic load models for bridge decks with sufficient accuracy using computational methods. The fluid mechanics laboratory has four wind tunnels. The largest wind tunnel is frequently used for wind tunnel testing of bridge decks.

The wind tunnel testing of the DeMarcay Condominium tower showed structural wind loads in the critical direction that were around 80% of those that would be calculated by code approaches. Similarly, the local pressures were below code values over the vast majority of the building envelope with the exception of one small area at the lower floors where the tested loads were higher than the code Wind tunnel testing is an integral part of the design process in many industries. Whether an object is stationary or mobile, wind tunnels provide insight into the effects of air as it moves over or around the test model. Since the physics of flight depend on the proper flow of air to produce lift and reduce drag, wind tunnel Rotary balance wind tunnel testing grew out of rudimentary spin testing that began at NACA Langley in the 1920s. While wartime testing focused on military configurations, peacetime offered researchers the opportunity to establish testing and modeling techniques and exploration of dynamic scaling effects3. These wind tunnel tests took part over two weeks, exposing the hardware to wind speeds from zero to over 90 knots, with 14 hours of powered propeller operation. Photo Credit: NASA.

The larger open loop wind tunnel has a Plexiglas test section measuring 60.9 x 40.6 x 8.2 cm, making it big enough to take two heat sinks side-by-side. The fans are tray-mounted so they can be changed to provide the air flows of up to 10 m/s (2000 ft/min).
