Ever since the beginning of aviation, there has been an unwavering desire to improve airfoil design in order to improve aircraft performance. This insatiable desire for improvement has driven innumerable aerodynamicists to create a diverse range of revolutionary airfoils. This research investigates a revolutionary method to airfoil design, inspired by the complicated structures and aerodynamic qualities of natural leaves. Using biomimicry, the project seeks to increase the performance and efficiency of standard airfoil forms by modifying and incorporating leaf-like elements. The leaf’s coordinates are retrieved using image processing techniques and then loaded into the ANSYs design modeller. Computational fluid dynamics (CFD) simulations are performed using ANSYs Fluent to investigate the complex fluid motion of leaf-based airfoils made of Carbon Fibre Reinforced Polymer (CFRP). Velocity, pressure, and turbulence contours are presented for various leaves, and metrics such as lift coefficient, drag coefficient, and lift-to-drag ratio are calculated at different angles of attack. The comparison of the leaves shows promising improvements in lift-to-drag ratio and performance, implying possible applications in aircraft and wind turbine technology. The results conclude with implications of this bio-inspired CFRP airfoil has optimizing aerodynamic performance, reducing the impact of non-Newtonian fluid boundary layer effects and minimizing the flow separation with greater shear strength.

Keywords: Carbon fibre-reinforced polymer, Non-newtonian fluid characteristics, foliage airfoil, flow visualization, turbulence
