Recognition, classification and mechanical description of debris flows

[1] The rheological properties of suspensions containing high solid fractions are investigated. Attention is focused on viscosity of silicate and magmatic melt systems. A general empirical equation which describes the relative viscosity of suspensions as a function of suspended solid fraction is proposed. In the limit of very dilute solid concentrations it reduces to the Einstein equation. The proposed relationship is satisfactorily applied to reproduce available experimental data relative to silicate melts. Moreover, the extrapolation of the model to very high concentrations is compared with experimental observations on partially-melted granite.

Viscosity of high crystal content melts : Dependence on solid fraction

A model is proposed which is able to predict the maximum particle packing density (φm) over a wide variety of ceramic suspensions with very large difference in particle size/shape, particle surface chemistry, and solvent chemistry. This model provides a simple method to obtain φm directly through the use of a few viscosity-concentration data for a given colloidal suspension, rather than a best-fitting approach. The model is also capable of predicting the viscosity of a variety of ceramic suspensions under different conditions of shear. A comparison with some existing viscosity model is also presented.

Surface interactions of dimethylsiloxy group-modified fumed silica

A method is proposed for determining the shear viscosity behavior of highly concentrated suspensions at low and high shear-rates through the use of a formulation that is a function of three parameters signifying the effects of particle size distribution. These parameters are the intrinsic viscosity [η], a parametern that reflects the level of particle association at the initiation of motion and the maximum packing concentrationΦ
m. The formulation reduces to the modified Eilers equation withn = 2 for high shear rates. An analytical method was used for the calculation of maximum packing concentration which was subsequently correlated with the experimental values to account for the surface induced interaction of particles with the fluid. The calculated values of viscosities at low and high shear-rates were found to be in good agreement with various experimental data reported in literature. A brief discussion is also offered on the reliability of the methods of measuring the maximum packing concentration.
