Abstract
The relation between Lagrangian time scale and Eulerian turbulent characteristics is considered theoretically using the simple model of space-time correlation coefficient of turbulent velocity. Introducing the non-dimensional variables, the non-dimensional parameter α composed of Eulerian turbulent characteristics is derived. Then we discuss the relation between Lagrangian time scale and the non-dimensional parameter α. Numerical simulations of turbulent diffusion are made in order to prove the theoretical results.
