Telegraph-type versus diffusion-type models of turbulent relative dispersion
Kentaro Kanatani, Takeshi Ogasawara, Sadayoshi Toh
Properties of two equations describing the evolution of the probability density function (PDF) of the relative dispersion in turbulent flow are compared by investigating their solu…

Turbulent Relative Dispersion in Two-Dimensional Free Convection Turbulence
Takeshi Ogasawara, Sadayoshi Toh
The relative dispersion process in two-dimensional free convection turbulence is investigated by direct numerical simulation. In the inertial range, the growth of relative separati…

A new model of turbulent relative dispersion: a self-similar telegraph equation based on persistently separating motions
Takeshi Ogasawara, Sadayoshi Toh
Turbulent relative dispersion is studied theoretically with a focus on the evolution of probability distribution of the relative separation of two passive particles. A finite separ…
