Abstract

Analysis of flows in grooved micro-channels has been carried out. One-dimensional grooves with arbitrary orientation with respect to the channel axis have been considered. It is shown that the drag generation mechanisms can be divided into effects associated (i) with the average position and (ii) with the shapes of the grooves. Three physical mechanisms associated with the shapes have been identified, i.e., re-arrangement of viscous stresses, pressure interaction drag and pressure form drag. Analysis relies on the analytic solutions in the limit of long wavelength corrugation and a novel, grid-less, spectrally-accurate algorithm based on the Immersed Boundary Conditions (IBC) concept for other corrugations.
