Next generation aeroacoustically and aerodynamically efficient aerofoil

Applications are sought for a self-funded PhD student to undertake a 36-month research into fan broadband noise reduction at Brunel University London.

This project represents an exciting opportunity to work towards the application of structured porous surface to reduce aerofoil broadband self-noise and improve the aerodynamic performances. It will involve the design/optimisation of the structured porous surfaces, commissioning their fabrication, integration to aerofoil fan blades, wind tunnel testing, data acquisition, data analysis and physical interpretation.

Fan broadband noise (turbulence-leading edge interaction noise, and trailing edge self­ noise) is typically encountered in aero-engines, wind turbines and home-appliances. Other noise sources include the broadband deep-stall noise when the fan blade is operated at high loading configuration. This project seeks to control the turbulence generation mechanisms, and suppress the large-scale boundary layer separation by the structured porous treatments, with the eventual aims of reducing the fan broadband noise, understanding the physical mechanisms and improving the aerodynamic performances.

The research will mainly be conducted at an aeroacoustics wind tunnel facility at Brunel University London. The PhD student will receive support from all members of the friendly project team, including technical support from the departmental technicians.

The applicant should already have, or about to complete, a Bachelor or Master degree in Aerospace or Mechanical Engineering. The applicant should have good understanding in the area of aerodynamics and fluid mechanics. Experience in the area of aeroacoustics is desirable but not essential.
