Abstract
A wind tunnel device may include a waste disposal unit configured to collect fluid from a droplet extractor positioned in a wind tunnel. The waste disposal unit may include a drain line and a liquid trap integrated in the drain line. The liquid trap may be adjustable during operation of the wind tunnel to accommodate different tunnel operating conditions (e.g., wind speeds) such that liquid waste does not backflow into the wind tunnel.

14. A method of disposing waste from a wind tunnel, the method comprising:
-
circulating air through the wind tunnel at a first wind speed; setting a liquid trap at a first height in response to the first wind speed to inhibit backflow of fluid into the wind tunnel at the first wind speed; adjusting the wind speed in the wind tunnel to a second wind speed that is different from the first wind speed; and adjusting the height of the liquid trap to a second height that is different from the first height in response to the second wind speed to inhibit backflow of fluid into the wind tunnel at the second wind speed. - View Dependent Claims (15, 16, 17, 18)

19. A wind tunnel device comprising:
-
an extractor reservoir configured to collect fluid from a droplet extractor positioned in a wind tunnel; a waste container configured to collect fluid from the extractor reservoir; and a liquid trap fluidly connecting the extractor reservoir to the waste container; wherein the liquid trap is adjustable during operation of the wind tunnel to enable drainage of the extractor reservoir and inhibit backflow of fluid from the waste container regardless of the operating speed of the wind tunnel.
