Recently, we also had automotive weeks in the tunnel. Lausitz Dynamics had come again (for real drag measurement this time), and Elbflorace have done some oil painting and pressure estimation. We used the opportunity to shoot some streamlines by ourselves. To do this, a heating wire had been installed vertically in the wind tunnel nozzle. Oil was applied on the wire, once it is heated, the fluid will form droplets that vaporize and are taken away by the flow where they condensate again, visualizing the traces of the flow. Although only weighing 36 kilograms, the LaDy was lifted into the test section with the crane. On the way back she was simply carried by two students. Standing besides Murph-E, which is a very small car anyway, this LaDy still looks even smaller. It is said that Murph-E (electrical), last years formula student race car of the Elbflorace team, often worked according to Murphy's law ;).
