But a full-sized wind tunnel is going to cost a small fortune, so how can we experiment? Never fear, because [luisengineering] is here with <a href=\"https:\/\/makerworld.com\/en\/models\/2838210-desktop-wind-tunnel#profileId-3163639\" target=\"_blank\" rel=\"nofollow noopener\">a 3D printable desktop wind tunnel<\/a>.<\/p>\n<p>There\u2019s a build video that we\u2019ve embedded below, and if you can sit through the continuous shilling of random tools, it\u2019s an interesting watch. It\u2019s an open design in that air is not recirculate through it, instead it passed through the machine from left to right. On the right is the fan, on the left the intake with a rectifier to ensure laminar flow. Then a constriction compresses and speeds up the air past the stage for the model under test, and an expansion slows it down again for the fan.<\/p>\n<p>A wind tunnel needs a smoke generator to easily spot turbulence, and in this case a vape is called into action. The result is surprisingly effective, as we see with a demonstration using a small model car.
