... Dynamics (CFD) results and Test data. Effective shear rates in the porous media were obtained from fluid velocities at media face and porous media grade. It was observed a consistent shear thickening behavior. Results of applying this viscosity correlation, at the filter design stage, gave us a much better...

... Abstract Mineral dissolution in porous media coupled with single- or multi-phase flows is pervasive in natural and engineering systems including carbon capture and sequestration (CCS) and acid stimulation in reservoir engineering. Dissolution of minerals occurs as chemicals in the solid phase...
