Girls Visualizing Flow
On April 23, 2015, the ITN Cowet and the SFB TRR 150 provided six girls between 11 and 17 years with exciting insights into the research at the TU Darmstadt wind tunnel facilities.
Mechanical Engineering is a male domain? During this year’s “Girls’ Day”, six pupils had the opportunity to be convinced otherwise: The day began with a tour through the TU Darmstadt wind tunnel facilities. The girls were explained the two low-speed tunnels and got to know the history of the building.
In the lab, members of the two collaborative research projects held a talk on the history of fluid mechanics and described their job as scientists. Together with the scientists the schoolgirls then conducted flow visualization experiments:
Why do water droplets bead on certain surfaces while they stick to others and how do chemical agents influence wettability?
How can flows around an air foil section be visualized? What exactly happens when a balloon filled with water bursts? The high-speed camera shows how droplets steadily change their shape and hover around in slow motion. This is not only pretty to look at but also enables the scientists to measure the size and velocity of the swirling droplets.
As a leaving present each participant was given a bag with literature and a pen drive containing images and videos of their own experiment.
At Girls‘ Day companies, businesses and universities in Germany open their doors for students from the fifth to tenth grade. The girls get to know occupations requiring training and course of studies in the IT, crafts, natural sciences and technology sector where women are underrepresented.
