Calming the Superfluid Storm: Taming Turbulence in Superfluid Devices

湍流，即流体的混沌流动，在自然界中的绝大多数流体流动中都会发生。这个项目旨在对超流体中的湍流有一个新的理解，超流体是一种可以无摩擦流动的量子流体。其重要意义在于，湍流的各个方面都是普遍存在的，因此在超流体湍流中的发现将为我们提供对所有形式的湍流的基本见解。预期的结果是两个悬而未决的问题的解决方案-超流体湍流的普遍定律是什么，以及哪些新形式的量子涡旋物质是可能的？对湍流的新见解将使所有依赖于它的理解的应用程序受益，例如在医学、航空和气候建模方面。

Turbulence, the chaotic flow of fluids, occurs in the vast majority of fluid flows in nature. This project aims to develop a new understanding of turbulence in superfluids, a class of quantum fluids which can flow without friction. The significance is that aspects of turbulence are universal, so that discoveries in superfluid turbulence will provide fundamental insights into all forms of turbulence. The expected outcomes are solutions to two outstanding questions – what are the universal laws of turbulent flow for superfluids, and what new forms of quantum vortex matter are possible? New insights into turbulence will benefit all applications which rely on its understanding, for example in medicine, aviation, and climate modelling.
