Flow development of wake behind Sierpinski tetrahedron has been investigated. The Sierpinski tetrahedron is a three dimensional object of which fractal dimension is 2. Blockage ratio of the Sierpinski tetrahedron over cross section of wind tunnel is 100%. It is found that the fractal object can has an ability to generate relatively high Reynolds number based on turbulent intensity and Taylor microscale (Reλ = 155) even with the small scale wind tunnel of the present study.
