Resumen
Flow electrification is a complex phenomenon and, in spite of extensive researches for many years by several groups all over the word, the origin of the process is not totally clarify. Indeed, even if the influence of many parameters has been established. However, the physicochemical process at the interface solid/liquid remains rather difficult to clearly understand because it is often controlled by impurities which are not well identified. Concerning the influence of the flow characteristics, it has been pointed out in various experiments that the wall shearing stress plays an important role on the ionic exchanges at the interface which control the wall current density. In this paper we analyze this behavior comparing the different experimental results that we previously obtained. Finally, we discuss the relation between the wall shearing stress and the wall current density.
