摘要：

A Langevin model with binomial random diffusion replacing the classical Wiener process is proposed to model the turbulent mixing of a scalar convected by a field of statistically homogeneous turbulence. A Monte Carlo simulation is performed. The results display an excellent agreement with existing data from the numerical experiment of Eswaran and Pope [Phys. Fluids 31, 506 (1988)].
