Environmental phenomena – including the weather – involve flows of various fluids. Many industrial processes involve flows of fluidswhetherwithin large-scale plants such as oil refineries or micro and nano fluidics, e.g. in ‘laboratory on a chip’ devices. But such flows of matter are also encountered in less familiar contexts such as in cosmology and in elementary particle physics – quark-gluon plasmas. Given such a breadth of contexts, there is a major challenge in finding accurate and… Expand
