Classical Turbulence in Cryogenic Helium

Fluid turbulence is important in numerous applications, and is a model system for nonlinear systems with many degrees of freedom. The equations of motion are not easily amenable to analysis and for this reason progress in the field requires significant effort in experiments and in numerical simulations. In recent years, some progress has been made utilizing helium at low temperatures, enabling high-Reynolds number turbulence to be generated in laboratory experiments. With high Reynolds numbers, however, come new challenges for measurement.
