Abstract

In this study, experimental work in the literature about friction on bird-feather like structures has been reviewed and one of these was modeled by using CFD (Computational Fluid Dynamics) to obtain minimum grid parameters. Coupled with obtained optimal grid parameters, the shear stresses of the two-dimensional models were investigated at the values of Reynolds number 110,000-470,000. Based on the concluded previous study, three-dimensional geometries were modeled with reference to two-dimensional models and analyzed with the determined grid structure. The results of the analysis are compared with those of the previous experimental study in the literature. In the final phase of the study, a drag reduction was found to be approximately 30% on the surfaces inspired by bird feathers.
