Investigating Fluid Transport Correlations in Partially Filled Pipes

Chris is an NNL research technologist based in the characterisation and rig operations team at Workington. He has experience working in R&D projects, both theoretical and experimental, relating to the hydraulics and fluid dynamics of nuclear waste transport. He undertook his PhD at NNL’s Centre of Innovative Nuclear Decommissioning (CINDe) graduating in 2022. His work focused on investigating slurry transport correlations in partially filled pipe flows by large-scale experimental techniques. This resulted in developing a framework to underpin the pipeline transport of fluids associated with the nuclear industry by a novel flow correlation (the Cunliffe correlation / FRESCO). Since completing his PhD, he joined NNL’s post-doctorate program and has worked in collaboration with customers to apply this new equation to their many different scenarios within the nuclear industry. He is an honorary research associate at University of Liverpool and industrial supervises a number of PhD projects.
