Studies of Intensified Small-scale Processes for Liquid-Liquid Separations in Spent Nuclear Fuel Reprocessing

Dimitrios Tsaoulidis is a chemical engineer with expertise on intensified two-phase processes particularly relevant to spent nuclear fuel reprocessing. The main aim of his research, which combines sophisticated experimental and modelling methodologies, is to provide insight into the fundamentals of two-phase flows, study the interaction with mass transfer, as well as develop models for accurate prediction of the process' performance. The research is facilitated by state of the art devices, equipment, and techniques, which include among others small scale setups, laser based instruments (PIV, shadowgraphy), high speed cameras, conductivity probes, etc.
