Analysis of the slip condition in magnetohydrodynamic (MHD) micropumps

In this paper, the consequences of considering fluid/wall slippage in magnetohydrodynamic (MHD) micropumps are explored by analytical and numerical calculations. One- and two-dimensional flow models commonly used to describe MHD micropumps, are revisited by assuming the slip condition in low-Hartmann-number flows. Different combinations of slip and no slip conditions at the walls of the micropump are investigated, and the influence of the slip length on the flow rate is analyzed. (C) 2012 Elsevier B.V.
