High-pressure setup unlocks detailed measurements of organized structures in turbulent flows
Turbulent flows are ubiquitous: they are found in clouds, in the ocean and even on other planets. Yet despite their chaotic nature, they also form large-scale structures that can be calculated and predicted. For example, while long streaks of clouds may appear orderly from the ou
