Abstract

A new model for thermal dispersion is proposed based on the character of flow in porous media which relates the dispersion with the velocity and the tortuosity of fluid flow in the pores. Compared with former similar models, this one has fewer adjustable empirical constants, and therefore it is expected to be used more conveniently. The prediction by the present model can successfully reproduce the temperature distributions in the nearby wall region when a single phase fluid flows through a packed channel. The results of Nu versus Re agree well with the experimental results. © 2003 Wiley Periodicals, Inc.

## Abstract This work is to prove the Hölder continuity of the solutions of the degenerate differential equations describing two‐phase, incompressible, immiscible flows in porous media. The differential equations allow degeneracy at two end points and the assumption on mild degeneracy is not requir
