Eulerian—Lagrangian relationships in monte carlo simulations of turbulent diffusion

A Monte Carlo technique for simulating turbulent diffusion is developed based on the Eulerian space-time velocity autocorrelation function. This method is an improvement over the usual Lagrangian approach since the Eulerian statistical properties of the turbulence are more easily measured. The analysis leads to some simple analytic relations between Eulerian and Lagrangian integral scales.
