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 outside, their interiors are characterized by intense turbulence.<\/p>\n
The high-pressure chamber at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS), nicknamed the \u201csubmarine,\u201d makes it possible to better understand the formation of these large-scale structures. Headed by research group leader Stephan Weiss and Director Eberhard Bodenschatz, the physicists have designed a special setup for such measurements. Their work is published<\/a> in the Review of Scientific Instruments.<\/p>\n \u201cThe challenge is to generate flows with particularly strong turbulence, similar to those found in nature,\u201d says Weiss. In their setup, the team uses a rectangular convection cell measuring 3.5 m long and 0.7 m high, whose temperature at the bottom and top can be regulated very precisely using heating and cooling plates. The experiments are conducted in a heavy gas (sulfur hexafluoride) at a pressure of up to 19 bar to replicate the large-scale turbulent flows found in nature on a smaller scale.<\/p>\n","protected":false},"excerpt":{"rendered":" Turbulent flows are ubiquitous: they are found in clouds, in the ocean and even on other planets.
