When a liquid is in contact with a solid, a physicochemical reaction occurs at the solid-liquid interface leading to the formation of the electric double layer. Whenever the mobile portion of this charge inside the liquid ...

This paper deals with flow electrification phenomenon of liquids in channels of rectangular cross section. Different theoretical models are described and compared. For all the models, it is assumed that the flow and the ...

Flow electrification is a complex phenomenon and, in spite of extensive researches for many years by several groups all over the word, the origin of the process is not totally clarify. Indeed, even if the influence of many ...

This paper deals with flow electrification phenomenon for turbulent flows of liquids through pipes of a circular cross section. Two models are proposed. The first one is based on the comparison of the radial fluctuant ...

As soon as a liquid comes into contact with a solid, physicochemical reactions occur at the solid-liquid interface to form an electrical double layer. According to the classical theory, it is assumed that the laminar flow ...

In this paper we analyze some experiments made previously on streaming current in glass capillaries. As the "classic Poiseuille flow" and the hypothesis of smooth pipes do not seem to give a good agreement with the ...

Kinematic viscosity and electrical properties (permittivity and electrical conductivity) of biodiesel samples were determined in the temperature range between 298 K and 343 K. The samples were produced from sunflower, ...
