Abstract :
An analysis is presented of the fluctuations of the potential difference between two parts of metallic tube insulated to each other and through which a dielectric liquid is flowing with a turbulent flow. First, the phenomenon of the convection of the double layer appearing at the contact solid/liquid and in the case of a turbulent flow is described. Then, the expected reasons of the potential fluctuations existing are proposed. Equipment is developed to measure the potential difference, and the experiments are presented and discussed.<>
