Abstract:
Experimental data used to determine the friction factor in microchannels are presented. Glass microchannels with a circular cross section, diameters of $34.5$, $33.6$, and $24.5$ $\mu$m, and different lengths are studied in the experiments. Pure deionized degassed water is used as a working fluid. The range of the Reynolds numbers is $13\le\mathrm{Re}\le330$. A method of two channels is used to calculate the friction factor. The results obtained are in good agreement with theoretical predictions for the case of a developed laminar flow in circular channels, but the use of the method of two channels has some constraints.
Keywords:
laminar flow in microchannels, friction factor, microflows.
