Abstract
Turbulence generated through 3 dimensional Fractal structure object was investigated.Four variations of the Sierpinski tetrahedra were chosen to examine the effect of lacunarity,arrangement and number of iteration on the turbulence decay. Turbulence generated by all structures decays with power law after initial development. However, the original Sierpinski tetrahedron and the one with different lacunarity showed exponential decay and accelerate the decay in the farther downstream.
