✦ Synopsis

An asymptotic technique is used to derive the functional dependence of effective viscosity on concentration for a suspension of uniform solid spheres, in the limit as concentration approaches its maximum value. This result, containing no empirical constants, is intended to complement the classical Einstein formula which is valid only at infinite dilution. Good agreement is found between the asymptotic solution and available data, provided that the maximum concentration is determined from the data themselves.
