About the project
This PhD tackles the challenge of understanding turbulent emulsions, which is crucial for developing cleaner, more efficient industrial processes. Using cutting-edge experiments, computer vision and machine learning, you’ll generate unique data to build predictive models of droplet dynamics, advancing both fundamental fluid mechanics and sustainable process engineering.
Predicting the behaviour of turbulent dispersed multiphase flows, where droplets or bubbles are suspended in another fluid, is crucial for processes such as rain formation, wastewater treatment, oil recovery and biofuel synthesis. A major challenge is modelling how droplets break up and coalesce, since this depends on local turbulence and is difficult to measure experimentally.
This PhD will address this challenge by developing high-fidelity experimental datasets to inform and validate models of droplet population dynamics. The project will involve designing and operating a Taylor–Couette flow rig using Refractive Index Matching (RIM) to generate optically accessible turbulent emulsions. Advanced Particle Tracking Velocimetry (PTV) and Laser-Induced Fluorescence (LIF) measurements will be combined with modern Computer Vision (CV) and Machine Learning (ML) methods to quantify droplet size distributions and local turbulence characteristics.
You will join a thriving research community of over 50 PhDs, postdoctoral researchers and academics within the Aerodynamics and Flight Mechanics Group, gaining access to a world-class experimental fluid mechanics laboratory equipped with state-of-the-art flow diagnostics. The project offers specialist training in optical measurement techniques, scientific computing, and data-driven modelling - preparing you for careers in academia or industry.
You will also have opportunities to publish in leading journals, present at international conferences, and collaborate with global research partners.
