Abstract : A free boundary problem that generalizes slightly the equations modelling the flow of two immiscible fluids in a one-dimensional porous medium is studied. One seeks a curve s(t), representing the interface between the liquids, and a function u(x,t), representing-after a change of variables-the pressures of the fluids.
