Mechanical flaps in the wind-wave tunnel push nearly 3,000 gallons (11,400 liters) of water through the 45-foot-long (14-meter-long) tank, while fans generate wind speeds as high as 90 mph (145 km/h), roughly the speed of a Category 1 hurricane.
While the waves can be heard outside the tunnel, the turbulent conditions are contained within its clear acrylic walls. Elevated above the ground and resembling a very long aquarium, the tunnel is about 6 feet (1.8 meters) tall and 3 feet (0.9 meters) wide. In the dark, under purple lighting, a ribbon of uniform waves puts on a mesmerizing show as researchers capture data using high-speed cameras and lasers.
The wind-wave tunnel allows researchers to conduct controlled experiments to study how the ocean and atmosphere interact. Research conducted in the facility could help improve hurricane forecasting and help scientists understand how wind and waves interact with offshore structures, from solar panels to aquatic robots and unmanned surface vehicles. "The ocean is an incredibly complex environment, and it's difficult to isolate individual processes when conditions are constantly changing," said Dr.
Kianoosh Yousefi, assistant professor of mechanical engineering in the Erik Jonsson School of Engineering and Computer Science. "This facility allows us to re-create those interactions in a controlled environment so we can better understand how wind and waves influence one another." Yousefi is studying how sea spray could affect the intensity and evolution of hurricanes. His team has been developing a machine-learning model to improve hurricane forecasting as part of a project.
The wind-wave tunnel gives students the opportunity to gain experience with experimental techniques to visualize and measure air movement, breaking waves, droplets and bubbles. Lasers and cameras help researchers make invisible air and water movement visible. Particle image velocimetry tracks tiny tracer particles to map the movement of air and water.
Laser-induced fluorescence uses fluorescent dye to visualize the shape and movement of breaking waves. In addition, high-speed cameras and shadowgraphy allow researchers to capture tiny droplets and bubbles generated by waves. "The nice thing about this facility is that it's hands-on," said Moaz Bilto, a mechanical engineering doctoral student.
