Decaying Turbulence and Anomalous Dissipation

摘要

In this contribution, we present results from an investigation of the normalised dissipation rate in decaying homogeneous isotropic turbulence. Due to the time-dependence of this system, it is necessary to find a time that indicates an evolved state of turbulent decay. We establish criteria for determining such times and use these to make measurements on our system. It is found that these criteria give results which are compatible with those of the current literature.
