Others Like “Showing the Airflow in a Wind Tunnel”

Science Fair Project Idea
Winglets are the short vertical "fins" at the wingtips of some airplanes. Have you ever wondered why they are there? If you have access to a wind tunnel, you can build model airfoils with and without winglets and see for yourself. If you're really ambitious, you can also build your own wind tunnel. Read more

Science Fair Project Idea
thumbnail Have you ever wondered why golf balls have a pattern of dimples on their surface? The dimples are important for determining how air flows around the ball when it is in flight. The dimple pattern, combined with the spin imparted to the ball when hit by the club, greatly influence the ball's flight path. For example, backspin generates lift, prolonging flight. When the ball is not hit squarely with the club, varying degrees of sidespin are imparted to the ball. A clockwise sidespin (viewed from… Read more

Science Fair Project Idea
Have you ever flown in an airplane, or looked up at one flying in the sky, and wondered how such a massive machine can stay in the air? Airplanes can stay in the air because their wings, also referred to as airfoils, generate lift. Engineers use devices called wind tunnels to experiment and test different wing shapes when they design new airplanes. Wind tunnels let engineers make careful measurements of the air flow around the wing, and measure the amount of lift it generates. If you can get… Read more

thumbnail Watch out! It's Eddy Vortex, Superhero! He swirls, he tumbles, he churns up air and water! OK, maybe eddies and vortices aren't exactly superheroes, but they are powerful regions of air and water flow that you have to watch out for in some surprising places. Try out this science fair project to discover why, as well as where and how to find them. Read more

Science Fair Project Idea
You can make a very simple hovercraft with a stiff, disposable plate-a pie plate should work well-and a balloon. Glue a square of cardboard in the center of the bottom of the plate. Make a small hole through the center of both of these layers. Enlarge the hole slightly with a pencil. Push a balloon through the hole so that the opening is on the front side of the plate, and rest of the balloon sticks out from the back. Blow up the balloon, then set the plate down (balloon side up). What… Read more

Time Required Long (2-4 weeks)
Prerequisites This is an advanced project that will require substantial initiative to design, build, and test. The experimental procedure gives outlines for how to proceed, and includes pictures; but precise details for the setup have to be worked out independently. Also, to perform the analysis, it is recommended that you first read the scientific papers that are listed in the Bibliography.
Material Availability You will need a web camera and a computer for this science fair project. See the Materials and Equipment list for details.
Cost High ($100 - $150)
Safety No issues

Try different wind turbine/propeller (chord length, pitch) designs by making models from balsa wood. Connect the spinning axle to a DC motor and measure the voltage produced across a resistor to measure power output. Use fan as wind source. (Judge, 2004) Read more

How much difference does the spiraling motion of a well-thrown football make on the distance of the throw (compared to wobbling, or end-over-end motion of the ball)? Think of a way to reproducibly produce the desired ball motion and launch it with a constant force to find out. (For more information on the physics, see Gay, 2004.) Read more
