ABSTRACT

In this study, we use the method of volume averaging to predict the exchange coefficient associated with steady laminar flow in a tube. This allows us to compare theory with an exact solution. Good agreement is obtained between the theory and the exact solution for the asymptotic condition, and this provides support for the simplifications that are made in the closure problem for transport processes in porous media.
