Reporting and new ideas for 2015 All our publications, theses, reports and presentations are available on our website: rescalemodelling rescalemodelling Direct observation of pore-scale displacement and assignment of pore- by-pore wettability. Emphasis on reactive transport imaging and modelling. Combining direct simulation methods into upscaled generalized network models.

Challenges for 2015 More accurate representation of complex media. Incorporating micro-porosity, or other features over a range of scales. Combining flow, transport and chemical reaction. Generalized pore-scale modelling an upscaling. View a network model as a generic upscaling tool, using direct simulation or experiment to assign effective properties. Integration with pore-scale experiments. Use imaging not simply to define the pore space, but assign contact angle, elucidate displacement processes and allow a pore-by-pore validation of models.
