Abstract
A two-fluid model to analyze the apparent slip phenomenon in Poiseuille flow is presented in this work. The model was formally developed on the basis of the fluid mechanics and provides a theoretical support for the phenomenological correction given by Mooney to account for slip in the Poiseuille flow. In addition, the model predicts a dependence of the slip velocity on the flow geometry, which is not considered in the Mooney correction but has been observed experimentally in some polymeric systems in the presence of apparent slip. Finally, the main differences with previous similar analyses by other authors are discussed.
