摘要：

A numerical method based on the polygonal approximation of Dafermos is applied to the solution of several problems of batch thickening within the framework of the Kynch theory of sedimentation. The method solves problems that cannot be approached by the theory of characteristics. (C) 1999 Elsevier Science B.V. All rights reserved.
