Improvement of Aerodynamic Performance of Aerofoil Design by Using Shark Skin Inspired Denticles

This research focuses on the passive modification of aerofoil surfaces to improve aerodynamic performance, particularly the reducing drag. The work is inspired by the drag-reducing properties of shark skin's tooth-like denticles. Simulation-based investigations were conducted to study the effects of incorporating novel denticle-inspired designs along one or both sides of an aerofoil. The objective is to analyse the impact of these denticle configurations on drag and lift. Using ANSYS Workbench, numerical simulations were performed on a 3D aerofoil model covered with shark skin inspired denticles. The simulations aimed to evaluate the aerodynamic performance of the aerofoil with denticle modifications. The focus was on assessing the effects on drag reduction and lift enhancement. The results of the simulations provide insights into the benefits of integrating denticle-inspired designs on aerofoil surfaces. By mimicking the drag-reducing characteristics of shark skin denticles, the modified aerofoil exhibited reduced drag and improved aerodynamic efficiency. The interaction between denticle geometry and flow characteristics was also investigated to understand the underlying mechanisms driving these effects. The findings demonstrate the potential of denticle-inspired surface modifications for enhancing aerofoil performance. The study highlights the importance of denticle geometry, such as size, spacing, and arrangement, in optimizing aerodynamic improvements. Furthermore, the simulation-based approach proves to be a cost-effective and efficient method for evaluating the effectiveness of denticle designs in drag reduction and aerodynamic enhancement. This research contributes to the field of passive control methods for reducing drag and improving aerodynamic performance. The insights gained from this study can be applied in various engineering applications. Further research can explore the practical implementation and optimization of denticle-inspired designs on aerofoil surfaces, expanding their potential impact in the field of aerodynamics.
