Turbulence generated through the Sierpinski tetrahedra was investigated. The Sierpinski tetrahedron is a model of foliage distribution of crown tree, and fractal dimesion of both strucures is two. Velocity ditribution in the cross section corresponds to the arrangement of the smallest tetraheda. Skewness of velocity fluctuation is positive in the lower speed region and vice versa, while flatness lies between 2.8 and 3.0 across the section. Taylor microscale based Reynolds number obtained was much greater than the corresponding grid generated turbulence. And the inertial subrange was observed.
