Turbulence is a complex phenomenon, characterized by many interacting degrees of spatial and temporal freedom. It is widespread, and indeed nearly the rule, in the flow of classical fluids. The complexity of the underlying equations has impeded analytical progress and therefore direct numerical simulations of the equations, as well as experimental work, are key to making further progress. Here, special attention is given to the role of low temperature helium as a test fluid, including the superfluid phase which also exhibits turbulence. |
