摘要：

This paper deals with streaming current generated by water flow through 4 geological porous media. These experimental measurements and a theoretical model allow to determine the space charge density pw at the wall in these 4 cases and to compare these values to previous ones obtained with glass capillaries and glass porous samples. The results show that pw is effectively the intrinsic parameter of the solid-liquid interface because it is not function of the geometry of the fluid flow paths but it only depends on the physico-chemical properties of the solid and the liquid.
