The setup of the surface flow visualisation by electrochemical deposit has given good results in the case of different flow types and in particular in the case of solids in rotation [1- 4]. This technique is based on the mass transfer principle towards a reactive surface electrode on which the studied flow will be visualised. This visualisation method of the surface streamlines by electrochemical deposit has allowed to understand the flow between a rotating and fixed discs. The inlet phenomenal named edge effects have been clearly seen during the visualization and the theoretical study. The purpose of this study is to precise the wide range from the surface streamlines configurations.
