Abstract

This project aims to bring together the novel and complementary research capabilities of UNICAMP and UNSW to investigate the technologically challenging problem of airfoil self noise. Airfoil noise is generated by aircraft (fan blades, high lift devices), wind turbines and cooling fans, which contribute to environmental noise pollution, identified as a global health problem by the WHO. Therefore it is important to understand and control airfoil noise to allow expansion of industry in harmony with society. Specifically, the PIs have identified an opportunity to collaborate through the combination of their unique computational and experimental expertise to shed new light on this complex scientific problem. Taking a lead from nature, they propose to mimic the behaviour of silent owl-wings by investigating poroelastic materials. The PIs further propose to organise scientific workshops in each country to foster greater scientific endeavour as well as develop an on-going research program to further investigate the fundamentals of airfoil noise production and owl-inspired noise control strategies.
