Measurement of streaming potentials [PDF]

Journal of Colloid and Interface Science, 1972
Abstract A method of measuring streaming potentials used by previous investigators was studied and evaluated. It was found that extraneous potentials, originating at the electrodes, interfered with streaming potential measurements in an unpredictable manner.

Analyses of electrokinetic energy conversion for periodic electromagnetohydrodynamic (EMHD) nanofluid through the rectangular microchannel under the Hall effects

Open Physics, 2022
Two-dimensional electromagnetohydrodynamic behavior of nanofluids through rectangular microchannels is investigated. The combined effects of time-periodic pressure gradients and magnetic fields in terms of the Hall effects on nanofluid flow are ...

Heat Transport of Electrokinetic Flow in Slit Soft Nanochannels

Micromachines, 2019
Soft nanochannels are defined as nanochannels with a polyelectrolyte layer (PEL) on the rigid walls. In the present study, the thermal transport properties of the fluids through slit soft nanochannels are investigated under the combined influences of ...

Streaming potentials at hydrocarbon reservoir conditions [PDF]

GEOPHYSICS, 2012
We have examined the behavior of the streaming potential under multiphase conditions, and under conditions of varying temperature and salinity, to evaluate the feasibility of using downhole streaming-potential measurements to determine fluid distributions in a reservoir.

Energy from streaming current and potential [PDF]

, 2004
It is investigated how much energy can be delivered by a streaming current source. A streaming current and subsequent streaming potential originate when double layer charge is transported by hydrodynamic flow.

Streaming Potential in Paper Chromatography [PDF]

Nature, 1949
THE net resultant flow of solvent through the capillary channels of paper used in chromatography is in a direction away from the point of feed, and it was therefore considered possible that such a system might result in the setting up of a streaming potential1.
