Abstract: This paper seeks for the line source and cylindrical plane source solutions of unsteady axisynmetrical two-dimensional flow through infinite and finite reservoirs with triple porosity. They not only reveal the essential characteristics of fractured reservoirs but also generalize and develop che existing primal results of homogeneous and porous media.Ref. [1] gives the line source solution of unsteady axi-symmetrical two-dimensional flow in infinite reservoir with double porosity; in this paper we study the problem of flow through triple porous media.

Key words: nonlinear evolution equation, FPU problem, similarity reduction
