Influence of Applied Potential on Wall-Bounded Water Flow

摘要

Measured potential dependences of flow velocities of aqueous hexafluorophosphate, perchlorate andchloride solutions bring to view velocity maxima, which are near the potentials of minima in earlierreported potential dependences of drag force. Earlier reported interfacial viscosity changes, calculatedfrom drag force data, are is to some extent overestimated due to leaving out of account theinterdependence of friction and pressure drags. The changes of interfacial layer properties, induced byapplied potential, extend beyond the interface and result in the bulk effects such as the change of wall- bounded flow velocity.
