Saffman-taylor problem
WebThe important feature of the present problem is that the fluid interface contains active particles, ... The Saffman–Taylor instability originates when a less viscous fluid is continuously pumped against a more viscous stagnant fluid in a Hele–Shaw cell. Thus, it exhibits fingers that consist of a less viscous fluid, ... WebThe use of surfactants represents a viable strategy to boost the removal yield of Dense Non-Aqueous Phase Liquids (DNAPLs) from groundwater and to shorten the operational timing of the remediation process.

WebThe well-studied selection problems involving Saffman--Taylor fingers or Taylor--Saffman bubbles in a Hele-Shaw channel are prototypical examples of pattern selection. Exact solutions to the corresponding zero-surface-tension problems exist for an arbitrary finger or bubble speed, but the addition of surface tension leads to a discrete set of solution … WebThis problem is about the instability and viscous fingering observed in the case of displacement through a porous medium of more viscosity fluid by a less viscosity one. This type of instability occurs if both fluids are viscous and they have different viscosity coefficients. This is called the Saffman–Taylor instability problem.
WebJul 25, 1997 · We study the minimal class of exact solutions of the Saffman-Taylor problem with zero surface tension, which contains the physical fixed points of the regularized (non-zero surface tension) problem. New fixed points are found and the basin of attraction of the Saffman-Taylor finger is determined within that class. Specific features of the physics of …
