The purpose of this paper is to evaluate the effective viscosity of a concentrated Newtonian suspension via spatially periodic approximation and to clarify the results from previously published articies. It is found that singular characteristic of the effective viscosity expression does not disappear. This approximation is then extended to investigate the system of a concentrated non-Newtonian suspension fluid. The results obtained by using the spatially periodic approximation are similar to that of a quasi-steady approximation in terms of the first order of e-1urthermore, the singular behavior also appears in the expression of the effective viscosity both for a second-order-Rivlin-Ericksen fluid at low shear rate and a Harnoy fluid at high shear rate, except that the viscoelastic effect in the low shear rate is depressed by spatially periodic approximation as compared with those orders obtained by quasi-steady approximation. |
