One of the most celebrated but least understood complex systems in nature is turbulent flow. This cross-disciplinary project aims to contribute to basic scientific knowledge of a class of turbulent flows, known as quasi two-dimensional fluids, that typically exhibit self-organizing properties, stable sheared flow, and relatively weak dissipation. The significance lies in the proposed testing, by modelling and simulation studies, of the well-grounded hypothesis that suppression of turbulence by sheared flow is a universal phenomenon in such fluids, and that it can be exploited to control transport of fluid constituents. Applications of this new knowledge will be developed.

自然界中最著名但最不为人所知的复杂系统之一是湍流。这个跨学科的项目旨在为一类湍流的基本科学知识做出贡献，称为准二维流体，通常表现出自组织特性，稳定的剪切流和相对较弱的耗散。的意义在于拟议的测试，通过建模和模拟研究，有充分根据的假设，抑制湍流剪切流是一种普遍现象，在这种流体，它可以被用来控制流体成分的运输。这些新知识的应用将得到发展。
