Abstract
This study investigated the effect of anisotropy of turbulence on the turbulent diffusion. Anisotropic turbulence was made by vortex stretching, and diffusion condition of CO2 were investigated. As a result, it was found that turbulence diffusion is proportional to total velocity fluctuation energy. It seems that the stretched longitudinal vortex and the anisotropy of turbulence cause this result.
