![]() ![]() There is a huge number of potential real-world uses for understanding macroscopic turbulence."ĭr Autti said quantum turbulence was a challenging problem for scientists. "Understanding that in classical fluids will help us do things like improve the aerodynamics of vehicles, predict the weather with better accuracy, or control water flow in pipes. Lead author Dr Jere Mäkinen from Aalto University said: "Our research with the basic building blocks of turbulence might help point the way to a better understanding of interactions between different length scales in turbulence. In the future, an improved understanding of turbulence beginning on the quantum level could allow for improved engineering in domains where the flow and behaviour of fluids and gases like water and air is a key question. This granularity makes quantum turbulence significantly easier to capture in a theory, and it is generally believed that mastering quantum turbulence will help physicists understand classical turbulence too. At small scales, quantum turbulence is different from classical turbulence because the turbulent flow of a quantum fluid is confined around line-like flow centres called vortices and can only take certain, quantised values. Quantum turbulence at large scales - such as turbulence around moving aeroplanes or ships - is difficult to simulate. ![]() The team's findings, published in Nature Physics, demonstrate a new understanding of how wave-like motion transfers energy from macroscopic to microscopic length scales, and their results confirm a theoretical prediction about how the energy is dissipated at small scales.ĭr Autti said: "This discovery will become a cornerstone of the physics of large quantum systems." There is a huge number of potential real-world uses for understanding macroscopic turbulence.ĭr Samuli Autti from Lancaster University is one of the authors of a new study of quantum wave turbulence together with researchers at Aalto University.
