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.
