Meteorological Wind Tunnel (MWT)

This is the most unique facility of the WEFL.  It permits the air and 40 ft (12.2 m) of the test-section floor to be independently heated or cooled and 70 ft (21.3 m) of the floor to be cooled for generation of thermally stratified flows.  The wind speed can be continuously adjusted in the range from 0 through 120 fps.  Other characteristics of MWT are listed in Summary Table.  To examine the elevation and plan views of MWT please click a thumbnail below.

The tunnel surface roughness, pressure gradient, and humidity can also be varied.  It is designed for basic research on flow characteristics of the atmospheric surface layer and applied investigations of atmospheric dispersion and wind effects on buildings and structures.
