Measurements of distribution of streaming electrification current inside pipe

The paper presents streaming current distributions measured in an overflow system in both laminar and turbulent conditions. These distributions were taken using a shifting spherical electrode connected with electrometer. For lower values of Reynolds number the profile of current is parabolic. For higher values of Reynolds number the profile is flattened. In this paper also charge density distributions were determined in both cases. In the turbulent regime the volume charge density is distributed in the pipe more evenly compared with the laminar regime.
