Computational Analysis of Bio-Inspired Transformations on Symmetrical Airfoils

This computational study delves into the potential of the Fibonacci Sequence and the Golden Ratio in enhancing the aerodynamic efficiency of symmetrical airfoils. The NACA 0012 airfoil—a well-known symmetrical profile—is used as the baseline for creating two novel airfoil geometries; one for each mathematical transformation. These transformations were scripted in Python andANSYS Workbench with SPEOS is used for performing 2D CFD simulations on the baseline and modified airfoils. The k − ω SST (Shear Stress Transport) turbulence model is used in ANSYS to achieve airflow simulation at a Reynolds number of 7.4 million. The lift-to-drag ratio values of these airfoils are calculated at angles of attack ranging from 0 to 15 degrees and compared to determine efficiency improvements. The results showed efficiency improvement of both modified airfoils at certain angles of attack.
