摘要：

As an extension of previous work by one author on the settling of ideal suspensions, we analyze the settling behavior of a suspension with two particle sizes. The solid flux density as a function of both particle concentrations is constructed. Using a finite difference method three initial and boundary value problems were solved showing the settling curves and the concentration profiles for each particle size. We conclude the work by extending the concept of a Kynch Sedimentation Process to a mixture of any number of ideal suspensions, each having a different particle size. An example for six particle sizes is analyzed in detail. Again the result is given as sedimentation cur-ves and concentration profiles for each particle size.
