Abstract
Exact analytical representations are obtained describing self-similar unsteady flows of multi-phase
immiscible fluids in the vicinity of non-circular, but constant strength, fronts. It is
assumed that Darcy's law holds for each phase and that the mobilities are known functions
of the saturations. Equivalent representations are obtained for Hele-Shaw cell flows that are
produced when a viscous fluid is injected into a region containing some other viscous fluid.
The fluids may be Newtonian fluids or non-Newtonian fluids for which the coefficients of
viscosity depend on the shear stress. Even though the flows are unsteady and two dimensional,
the representations are obtained by using hodograph techniques.
