Scaled down fractal tree model reduces the cost of experimental investigation on the flow field around a tree. It also allows the study to be conducted in controlled environment, namely in a wind tunnel, but one of the major challenges is to construct a tree model that resembles the real tree. We have constructed scaled down fractal tree models of the Yellow yellow Flame flame (Peltophorum pterocarpum) and the African mahogany (Khaya senegalensis) based on statistical data gathered through laser scanning on the real trees. The trunk and braches of the Yellow yellow Flame flame tree model is constructed using a simple fractal tree design where a branch is recursively split into 3 child branches successively over 3 iterations. Each level of child branch’s length is reduced by a fixed ratio. On the other hand, the trunk and branches of the African mahogany tree model is constructed based on the L-System generated Multiscale Tree Graph data structure (MTG) file format.
