液体中に発生する流動電流を決定する要因について

Abstract

In previous papers, it is reported that the magnitude of streaming current generation in flowing liquid through the pipe is given by the product of K, T and V^^^-. Where K is the factor which is determined from the combimation of liquid's and pipe's materials. T is the relaxation time constant in liquid and V^^^- is the average velocity of liquid in the pipe. However the factor K is not clarified enough up to the present day. Authors concluded, by experimental results, that K is mainly related to the construction of the electric double layer and the charging density δ at the solid surface is the most important quantity which determins K. In insulating liquid, δ is explained as follows, ie, δ=εκζ Where ε is the permittivity of liquid, κ is the reciprocal of the thickness λ of the electric double layer and ζ is the zeta potential at the solid-liquid interface.
