Abstract

A role of helicity in turbulent diffusions is investigated. Helicity is a typical quantity dealt in the sense of Eulerian description, but we are going to reveal a role of helicity through the lagrangian turbulent flows. In this study, we investigate temporal distributions of local helicity fields. Its ststistics will be compared to the statistics of lagrangian velocity and acceleration of the fluids. It would be said certain relations through the comparisions. As an application, study for the temporal helicity is applied for turbulent tran-port or diffusion problems such as heavy particle dispersion problem.
