Computer simulation of viscous fingering in a lifting Hele-Shaw cell with grooved plates
Sujata Tarafdar Soma Nag Tapati Dutta Suparna Sinha
We simulate viscous fingering generated by separating two plates with a constant force, in a lifting Hele-Shaw cell. Variation in the patterns for different fluid viscosity and lifting force is studied. Viscous fingering is strongly affected by anisotropy. We report a computer simulation study of fingering patterns, where circular or square grooves are etched on to the lower plate. Results are compared with experiments.
