| Abstract |
An Applied Technology Inc. (ATI) sonic of the type used by J. C. Kaimal at the Boulder Tower was tested in the large wind tunnel at the U.S. EPA Fluid Modeling Facility. The wind tunnel is approximately 6 ft high, 10 ft wide with a test section bed 60 ft long. The air speed in the tunnel can be varied from about 0.20 m/s to 7.0 m/s. The sonic probe was mounted near the center of the tunnel to study the effect of shadowing of the probe and mount as a function of azimuth angle at speeds of 1.0, 3.0, and 7.0 m/s. Experiments were performed to determine if there is a Reynolds number dependency of the instrument when the tunnel speed was varied from 0.20 to 7.0 m/s. Velocity correction curves were developed for the sonic using these data. These curves are somewhat different from those published by J. C. Kaimal. No Reynolds number dependency of the flow on the velocity components under maximum shadowing was found. |
