| Description | We were able to find the physical mechanisms in which noise and drag of an aerofoil can be reduced, with which the design of leading-edge and trailing-edge undulations can be optimised. |
| Exploitation Route | Through publications, workshop and conferences. |

| Description | Experimental studies of a NACA 65(12)-10 aerofoil with a sinusoidal leading-edge undulation (LEU) were carried out to simultaneously optimise its aerodynamic and aeroacoustic performances by considering the attached as well as the separated flow at the effective Reynolds number of 1000,000, where the maximum lift was increased without sacrificing drag or overall noise near and post stall angles. Further aerodynamic and aeroacoustic tests indicated that a combination of LEU wavelength of 30% chord and amplitude of 6% chord gave an optimum leading-edge undulation by considering the aerodynamic performance as well as the noise reduction. PIV measurements of the flow over the optimized aerofoil showed bi-periodic velocity fluctuations downstream of the LEU peaks that were associated with unsteady stall cell structure near the trailing edge. |
