    A theoretical model is proposed to describe the non-Newtonian behaviour of suspensions of aggregated particles. A self-consistent field approximation is used to estimate the mean radius of flowing fractal clusters in a simple shear field. A rheological law is then proposed in which four fixed physical parameters are involved. The variation of the fractal dimension of clusters with the flow is
