The global water sector is facing increasing challenges due to climate change and rapid population growth, with water and energy demand projected to rise by 55% and 80% respectively by 2050. Addressing the water-energy nexus is therefore critical for the design and operation of sustainable water systems. This project focuses on the often-overlooked issue of air entrapment in pressurised pipelines, which can compromise energy efficiency, system reliability, and water quality.

The research will investigate the negative impacts of trapped air, such as increased head loss, reduced flow capacity, and contamination risks, while developing practical strategies for air removal or control. By integrating experimental techniques (in collaboration with Deltares, a leading research institute), advanced numerical modelling, and cutting-edge tools like automated image analysis and machine learning, this project will deliver actionable insights for engineers and practitioners.

The findings will support international standards and industry practices, advancing the creation of safer, more energy-efficient water systems. Additionally, the project aims to develop digital simulation tools, potentially enabling the implementation of real-time digital twins to monitor and optimise water networks, improving infrastructure resilience and sustainability in a changing world.
