Several researchers have conducted careful reviews on the published experimental friction and heat transfer data in microchannels.They found that in many cases the experimental data of the friction factor and of the Nusselt number in Microchannels disagree with the conventional theories but they also appear to be inconsistent with one another.Also, the information in the literature does not point to unequivocal trends of variation or reasons of such trends.Some researchers proposed that the deviations between measured data and conventional predictions may be explained by the micro-scale effects.The following scaling effects in micro-flow devices can be identified: temperature effects, compressibility effects, rarefaction effects, viscous dissipation effects, electro-osmotic effects (EDL), channel surface conditions and experimental errors.
