Liang ZHAO, Linhua LIU,

Frontiers in Energy 2009, Volume 3, Issue 4,   Pages 381-388 doi: 10.1007/s11708-009-0057-2

Abstract: The effect of Joule heating on the steady state electro-osmotic flow in a closed-end micro-channel ispresence of Joule heating causes an increase in temperature and a decrease in viscosity in the whole micro-channelvelocity near the wall and an increase in fluid velocity at the central region in order to maintain a zero flowrate at the cross section of the micro-channel.pressure gradient is also studied, which is very important for the application of the closed-end micro-channel
