摘要：
A simple method for the two-dimensional description of the flow velocity profile of Newtonian liquids in narrow channels is presented. This procedure is applied to a few types of cross-sections used in field-flow fractionation because the solutions of the flow velocity profiles are necessary for the theoretical description of the separation process in which the flow plays an active role. Limitations of the approach are discussed, and published results on this subject are compared.
