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. WebDec 14, 2024 · A similar problem is encountered in some hydrodynamic instabilities in miscible fluids, where the growth rate is unbounded in absence of interfacial stresses and/or viscous dissipation. This is indeed the case of Saffman–Taylor, Rayleigh–Taylor and Kelvin–Helmholtz instabilities that will be discussed in the next sections.
