Phys.org  September 17, 2021 To measure turbulent flows the movement of tracers that are added to the fluid are tracked. The tracers spread over time, they move far apart, and every particle moves independently. To overcome these issues an international team of researchers (Switzerland, Italy, Sweden) used fibers instead of tracer particles. They created a computer simulation and added rigid fibers of different lengths, which kept the ends of each fiber apart at a fixed distance. By tracking how each fiber moved and rotated within the fluid over time, the researchers were able to build up a picture that encompassed […]
