摘要

本文介绍了在层流和湍流两种情况下溢流系统的流电流分布。当雷诺数较低时,电流的分布呈抛物线状。当雷诺数较高时,剖面变平。本文还测定了两种情况下的电荷密度分布。在紊流状态下,体积电荷密度在管内的分布比层流状态更均匀。

Distribution measurement of streaming electrification current in pipes
The paper presents streaming current distributions measured in an overflow system in both laminar and turbulent conditions. 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.
