Named &#8216;pseudo-turbulence,&#8217; these patterns are characterized by a universal mathematical relationship between the energy of flows of different sizes, and the frequency of their occurrence. This relationship has now been widely observed through 3-D simulations, but it is less clear whether it would still hold for 2-D swarms of bubbles. Through research published in EPJ E, Rashmi Ramadugu and colleagues at the TIFR Centre for Interdisciplinary Sciences in Hyderabad, India, show that in 2-D simulated fluids, this pattern changes within larger-scale flows in less viscous fluids.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2020-12-characterising-complex-d-swarms.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Characterising complex flows in 2-D bubble swarms<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When swarms of bubbles are driven upwards through a fluid by their buoyancy, they can generate complex flow patterns in their wake.
