UCD is Ireland's largest research-intensive university with over 30,000 students, and it’s Ireland’s leader in graduate education with approximately 7,000 graduate students. UCD’s major strategic research themes include Earth Science, Energy and Environment, Global Ireland, Health and Healthcare Delivery, and ICT. It has a major contractual track record in successive EU Framework Programmes. UCD’s Impact rating in Journals has increased by more than 58% from 2002-2011, with the number of publications more than doubling in the same period. UCD plays a leading role in pioneering knowledge transfer with commercialisation of research invention disclosures, patenting, licencing and setting up spin-out companies.

UCD is working on the computational modelling of 3 key phenomena of the melt conditioning process, including the macroscopic fluid flow and heat transfer of melt, the microscopic breakup of oxide clusters, and the nucleation and growth of intermetallic phase from the oxide particles, in the process of HSP. The UCD modelling work receives essential inputs from RecycAl experimentalists and, in turn, its modelling outputs directly help the design and process optimisation of the melt conditioning by predicting the value of parameters of interest.
Benefits expected from the participation in the project
The research outputs of UCD will lead to computational prediction of a variety of key parameters that are normally difficult to directly measure in experiments, which will directly aid the process optimisation of HSP. The computational model developed in the research will be the very first one ever that predicts the melt conditioning with HSP, and hence it’s a significant progress against the state-of-the-art of this modelling topic.
