A computational approach to coupled preferential electrical and moisture flow in porous materials

About the project

About the Project Electric currents are increasingly passed through the ground and construction materials to strengthen, drain or treat soils, to protect and repair concrete, to earth electrical infrastructure, and to image conditions beneath the surface. In each case, current flows through the water held in the material's pores, so its behaviour is coupled to the moisture distribution. At present, the models used to design and interpret such physicochemical systems typically consider the two processes in isolation. This project seeks to develop modelling approaches that simulate coupled electrical and moisture transport in porous materials at various scales, to predict where preferential flow develops and its consequences for the technologies that depend on it. This will be achieved predominantly through finite element analysis, with an emphasis on understanding the behaviour in soils and cementitious materials. Access to state-of-the-art simulation software, high-performance computing facilities, and experimental laboratories will facilitate comprehensive analysis and validation of the developed models, ensuring robust and reliable research outcomes. Engagement in this project will offer extensive opportunities for skill development and professional growth. Participants will gain hands-on experience in numerical modelling, coupled multiphysics simulation, porous materials, and programming, honing their expertise in advanced simulation techniques. Additionally, involvement in collaborative research endeavours and industry interactions will foster interdisciplinary knowledge exchange and networking, enhancing career prospects and contributing to the advancement of the field. Academic Criteria Candidates should hold or expect to gain a first-class degree or a good 2.1 (or their equivalent) in Engineering or a related subject.
