dc.description.abstract | The capillary rise of liquid on the surface, or `wicking?, has potential applications in biological and industrial processes such as transport of fluids, drug delivery, oil recovery and integrated circuit chip cooling. In this study we examine the wicking phenomenon on Silicon nanostructured surfaces fabricated using the interference lithography and metal-assisted chemical etching (IL-MACE) techniques. With these techniques, we synthesized different patterns structures (pillars and fins) of nanometer size with different sizes, heights, and orientations along the line of liquid flow (for nanofins) on a Silicon substrate. By balancing the driving capillary forces in the rough surface and viscous dissipation forces caused by the nanostructures, we are able to we are able to establish the dependence of ?, the drag enhancement factor, on the geometrical parameters of the nanostructures and come up with an equation to predict the wicking process without use of extensive empirical values. Excellent agreement between theoretical and experimental results was achieved. | |
