Abstract
The design philosophy, construction details, and operating characteristics of the EPA Meteorological Wind Tunnel are described. Measurements in the empty tunnel show that the mean velocity is uniform to within plus or minus 2% at any given cross section, at speeds as low as 1.5 m/s. The turbulence intensity in the empty tunnel is typically 0.5%. A 2-meter-deep boundary layer was obtained using elliptic wedge vortex generators and roughness on the floor. Measurements are presented showing that this boundary layer simulates, in both turbulence structure and dispersive characteristics, a neutral atmosphere boundary layer over rural terrain.
