Multiphase Systems

Research in multiphase systems studies the flow and phase interactions of multiphase mixtures, from liquid/liquid systems such as emulsions, to solid/air systems like fluidised beds or air/liquid systems like foams. Through a combination of advanced experimental technologies, mechanistic modelling and numerical simulations, fundamental understanding of the physical and transport properties of multicomponent mixtures is obtained from the micro to the pilot-plant scale, thus advancing the development of novel products, processes and decision support tools relevant to a variety of industrial sectors, from pharma and energy applications and to CO2 emission mitigation from diverse industrial sources’ through Carbon Capture Storage and Utilisation.
