- Resumen
Micro-channels are believed to open up the prospect of precise control of fluid flow and chemical reactions. The capillary effect can be used to pump fluids in micro-channels and the flow generated can dissolve chemicals previously deposited on the walls of the channel. In this work, numerical and experimental approaches have been developed to investigate the wall mass transfer rate generated by capillary driven flows (CD-Flow). The purpose of this work is to analyze the wall mass transfer rates generated by a CD-Flow in a micro-channel. The results have implications in the optimization and design of devices for biological assays. The correlation for Sherwood number, Reynolds number, contact angle and time is reported. This correlation can be a useful tool for design purposes of microfluidic devices that work with fast heterogeneous reaction and have capillary driven flow as passive pumping system. The numerical results have been confirmed by the experimental results.
