Acoustic Wind Tunnel

The Acoustic Wind Tunnel is a large, quiet, low mach number facility specifically designed for basic hydrodynamic and hydroacoustic investigations. Construction techniques and design flexibility allow the tunnel to support a multitude of test configurations. The test volume is acoustically anechoic and completely isolated, resulting in extremely low background noise levels. These features permit measurement of radiated noise forcing functions at full-scale Reynolds numbers in completely uncontaminated flow. The facility maintains standard air parameters and can be converted from closed flow to open flow using external louvers. Large access doors, cranes, and a flexible testing arrangement make this facility well suited for dual-use projects such as automobile or environmental flow studies.
