Bio-inspired corrugated aerofoil has better flow physics compared to traditional aerofoil in addition to less wear and high strength. For identifying the aerodynamics characteristics, lift and drag, a study has been done by varying angle of attack (AOA). Both low and high AOAs are analyzed for identifying the optimal flapping condition at constant Reynold number. CFD analysis is performed using ANSYS Fluent. 2D analysis is performed using k-ε model, and sphere of influence is utilized to capture the flow field and to reduce the computational cost. Results report that low AOA performs better due to high lift-drag ratio and less flow separation.
