International audienceIn this paper we investigate the effects of defects on the tortuosity of an homogeneousfluid saturated porous medium. These defects are modeled by porous inclusions which alter thesteady motion of the viscous fluid flowing in the medium. In this model the fluid velocity is solutionof equations deduced from the Darcy’s law in the host medium and in the inclusions, subject toboundary conditions at the interface between the inclusions and the medium. The shape of theperturbed fluid streamlines allows the determination of the tortuosity induced by the defects andits consequences on the acoustic wave propagation in this medium
