Pakistani engineering graduates can apply for a fully-funded PhD at the University of Southampton in the UK, focusing on computational fluid dynamics, aeroacoustics, and aircraft engine noise.
Research under the High-fidelity CFD for Fan/OGVs Broadband Noise Modelling project will examine how turbulent airflow from an aircraft engine fan generates broadband noise when it interacts with outlet guide vanes.
Rolls-Royce and the EPSRC Centre for Doctoral Training in Sustainable Sound Futures jointly fund the project. International students are eligible, and applications will close on September 1, 2027.

Why Aircraft Engine Noise Is the Main Research Focus
Modern Ultra High Bypass Ratio (UHBR) aero engines use larger and slower-moving fans as manufacturers work to improve aircraft efficiency and reduce noise.
However, these engine designs create new challenges for broadband noise prediction. Turbulent airflow left behind by the rotating fan interacts with stationary outlet guide vanes. This interaction produces broadband noise across a wide range of frequencies.
Current engineering models often simplify the behaviour of this fan wake turbulence. Such assumptions may not fully represent the complex airflow found in realistic aero engines.
Researchers at Southampton aim to identify which turbulence characteristics have the greatest effect on noise generation and improve the accuracy of future prediction models.
High-Fidelity CFD Using LES and DES
Advanced computational fluid dynamics will form a major part of the PhD. The researcher will use scale-resolving CFD techniques, including Large Eddy Simulation (LES) and Detached Eddy Simulation (DES), to model representative fan and outlet guide vane stages.
Analysis will cover turbulence intensity, integral length scales, velocity spectra, spatial coherence, and variations across the fan span.
Simulation results will also be compared with available experimental measurements to assess how accurately the CFD models reproduce real airflow.
Improving Broadband Aero Engine Noise Models
Acoustic analysis will examine how turbulent fan wakes create unsteady forces on outlet guide vanes and how these forces generate noise.
Researchers will investigate broadband noise across different frequencies and duct modes. Results from the simulations will help determine which turbulence statistics matter most for accurate noise prediction.
Those findings will then support improvements to semi-analytical engineering models, which can offer faster predictions than running full high-fidelity CFD simulations every time.
Researchers will compare the improved models with existing methods and experimental data.
