Simulation of Atmospheric Boundary Layer in an Open-Loop. A vane anemometer thus combines a propeller and a tail on the same axis to obtain accurate and precise wind speed and direction measurements from the same instrument. The speed of the fan is measured by a rev counter and converted to a windspeed by an electronic chip. Hence, volumetric flow rate may be calculated if the cross-sectional area is, Air streams through the tunnel, and into the test object or the sensor, at a controlled rate, usually driven by a fan. In performing aeronautical and automotive tests, wind tunnels move air over stationary objects to simulate objects traveling through still air. Industrial and laboratory wind tunnels ….
