摘要: We report a computer simulation study of viscous fingering patterns in lifting Hele-Shaw cell with grooves. Here circular or square grooves concentric to the plates are etched on lower plate. Experiments show that presence such affect formation fingers quite strongly. simulated pressure map generated grooved cells, when two separated constant force and compare experiments. Variation for different fluid viscosity is also studied.
