Abstract: Based on Krieger-Dougherty equation,a phenomenological model is proposed to describe the structure parameter and maximum packing fraction changing with shear.After determining the model parameters from the experiment of yield strees measurement at various packing fractions,the suspension viscosity at different shear stress and packing fraction could be estimated.
