Abstract

For this study, using the lattice Boltzmann method (LBM), we conducted flow‐field analyses in which two straight channels were mutually connected with multiple side‐channels. Results showed that calculated flow fields can be categorized into three types of flow pattern depending on flow field geometry and flow conditions. The following typical flow patterns were identified: case 1, the incoming flow passes uniformly through the side channels; case 2, the flow passes preferentially through the side channel in the inlet and the outlet; and case 3, the flow passes mainly through the side channel of the outlet side. Results also indicate that these flow patterns depend on two dimensionless parameters: the ratio of permeability of the side channels to the channel width, and the Reynolds number. © 2007 Wiley Periodicals, Inc.
