Eversince, the phenomenon of flow electrification observed for insulating liquids has been studied and its dependence on flow parameters and the pipe geometry has, in many varying cases, modelised and is now well known. However, in terms of the length of the pipe, a complete analysis taking into account the electrochemical reaction at the wall pipe-liquid interface has not yet been developed. In this paper, a modelisation of the process in the case of additives or impurities partially dissociated into positive and negative ions is presented. Comparison are made and discussed between this modelisation and experiments of flow electrification for hydrocarbons liquids.
