About the Project
Overview
A PhD studentship is now available to undertake research into the understanding and prediction of the broadband noise generated by the fan in aircraft jet engines. Fan broadband noise has become one of the dominant noise sources on an engine, particularly when the aircraft is at approach. There is now an urgent need to understand its noise generation mechanism in order to predict and hence control it. This studentship represents an exciting opportunity to work as part of a dynamic team of researchers working towards the common goal of understanding and controlling the many sources of aircraft engine noise. The student will be jointly supervised by Prof Phil Joseph of the Rolls-Royce University Technology Centre (UTC) in gas turbine noise within the Institute of Sound and Vibration Research (ISVR) and Prof Xin Zhang of the Airbus Aircraft Noise Technology Centre (ANTC) aeronautics dept. The studentship is funded by Rolls-Royce. Frequent interaction with the company is expected. In recognition of the importance of this work the standard PhD studentship stipend will be supplemented by a small bursary. The student will be expected to have a good first degree in physics, mathematics of engineering.
Details
Broadband noise is generated whenever turbulence interacts with solid surfaces. In an aircraft engine there are many situations when this can occur. The main source of fan broadband noise is currently believed to be due to the interaction between the turbulent wake shed from the rotor blades and the Outlet Guide Vanes (OGV’s) downstream whose purpose is to remove the swirl component of the flow imparted by the rotor blades. This PhD project will apply state-of-the-art numerical modelling techniques to predict the unsteady flow around the rotor blades and hence predict the broadband noise. As well as providing accurate predictions tools for industry the work will focus on establishing a detailed understanding of the noise generation mechanism in terms of fundamental physical principles.

Funding Notes
The studentships cover both basic engineering research and applied research, which fully cover University tuition fees and provide a tax-free bursary of £13,600 per year, rising annually (each October) in line with the UK Government (EPSRC) recommended rate, for a 3 year duration.
