From local and bulk structure-flow correlations to macro-scale transport properties with MRI: applications using deformable porous media and deep learning
… and linked to bulk transport properties such as permeability and dispersion. Three-dimensional (3D) spatially resolved flow MRI measurements combined with machine learning techniques, namely a feedforward artificial neural network (ANN), were employed to predict the absolute permeability of 21 …

Optimal scheduling, design, operation and control of reverse osmosis desalination. Prediction of RO membrane performance under different design and operating conditions, synthesis of RO networks using MINLP optimization framework involving fouling, boron removal, variable seawater temperature and variable fresh water demand.
… data which can be used for estimating the permeability decline factors. The correlation based on actual data to predict the annual seawater temperature profile is also incorporated in the model. The proposed optimization procedure identified simultaneously the optimal maintenance schedule …

Particle Detachment in Single-Phase and Two-Phase Flows in Porous Media
… and the attached-concentration-dependency of permeability. The new model captures the effect of permeability increase due to colloid mobilisation and further re-attachment in stagnant zones of the porous space. This effect was observed during high-salinity water injection in cores with low …
