89600 - Anisotropic Approach to Control Viscous Fingering Pattern Generated in Lifting Plate Hele-Shaw Cell 

In the crude oil extraction process, fluid instability is observed. Saffman and Taylor explored the concept of the Hele-Shaw cell to study these instabilities. Typically lifting plate Hele-Shaw cell involves a high viscous fluid sandwiched between two parallel plates and the low viscosity fluid is allowed to enter from the periphery. Insertion of low viscous fluid into a high viscous fluid generates a pattern that resemblance of a finger like pattern. This phenomenon is called viscous fingering. Viscous fingered formed basically represents least resistance path of low viscosity fluid. This study presents the techniques to control the instabilities and mimicked patterns available in nature. These instabilities can be controlled by controlling one of the fluids in the cell. This study reports controlling the flow of low viscous fluid (air considered in this study) by providing anisotropies in the form of holes and slots on any one of the plates of the Hele Shaw cell. This anisotropy guides air to interact with high viscous fluid at some desired location. The paper further presents the effect of size, position, the orientation of these holes and slots on the viscous fingering exhaustively. The presented technique provides the new avenue to fabricate the controlled micro sized finger type structures spontaneously with introduction of simple form of anisotropies.
