Calming the Superfluid Storm: Taming Turbulence in Superfluid Devices

湍流，即流体的混沌流动，发生在自然界中绝大多数流体流动中。该项目旨在发展对超流体湍流的新理解，超流体是一类可以无摩擦流动的量子流体。其意义在于，湍流的各个方面都是普遍的，因此超流体湍流的发现将为所有形式的湍流提供基本的见解。预期的结果是两个悬而未决的问题的解决方案-什么是超流体湍流的普遍规律，以及什么样的新形式的量子涡旋物质是可能的？对湍流的新见解将有利于所有依赖于其理解的应用，例如医学，航空和气候建模。

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.
