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