Flow control in micro-channels using groove orientation

Abstract

This paper is focused on the analysis of changes in the flow or pressure gradient induced by surface grooves, including the effects of shape of the grooves as well as their orientation with respect to the flow. The flow has been determined using a novel grid-less spectral algorithm based on the Immersed Boundary Conditions (IBC) concept, where the boundary conditions are submerged inside the computational domain and are treated as internal constraints. The results show strong dependence of pressure losses on the groove orientation. It is possible to reduce such losses, as compared with the smooth channel, by judicious selection of groove geometry and orientation.
