My research focuses upon the development of fast MRI imaging protocols and the application of these techniques towards the characterisation of multiphase flow. By designing sequences with an emphasis on robustness to fluid flow and shear, and using a compressed sensing reconstruction procedure applied to heavily undersampled acquisitions, it has proved possible to obtain high spatial and temporal resolution structural and velocity maps of a variety of systems. These data allow the fundamental hydrodynamic phenomena underlying the complex dynamics of multiphase flow to be non-invasively quantified for the first time. Systems of present interest are dispersed gas-liquid flow, turbulent single-phase pipe flow and liquid-liquid systems undergoing mass transfer.
