Fine scale turbulence

show research

Fine scale turbulenceRichard Fenynman described turbulence as the "most important unsolved problem of classical physics". It is inherently multi-scale with the finest scales, responsible for the dissipation of kinetic energy of the flow, often being predicted numerically as being "universal". This "universality" can be observed through the interaction between the strain-rate and the rotation on a fine-scale level across a variety of turbulent flows.

State of the art laser diagnostics now make it possilbe to produce fully three-dimensional data that is sufficiently well spatially ressolved to observe these fine-scale phenomena. The aim of this research is thus to scrutinise the assumption of the "universality" of fine-scale turbulence.
