Abstract

The objective of our study is to clearly identify the succession of the different flow regimes, to analyse their stability and to reveal the conditions of the appearance of the slip phenomenon, for a serie of silicon fluids. We also propose a simple but complete model of flow with slip at the wall specifying its application conditions.
