Abstract

The paper presents an analytically derived model of electrification phenomena in turbulent flow. Mechanisms of diffusion, convection, and conduction were taken into account. Distributions of current density where determined for the whole range of liquid conductivity and viscosity. The equations are derived assuming an isothermal incompressible Newtonian flow in a pipe in the steady state in time and space.
