Oscillatory Flow Through a Channel with Stick–Slip Walls: Complex Navier’s Slip Length
Effective slip lengths for pressure-driven oscillatory flow through a parallel-plate channel with boundary slip are deduced using a semi-analytic method of eigenfunction expansions and point matching. The channel walls are each a superhydrophobic surface micropatterned with no-shear alternating with no-slip stripes which are aligned parallel to the flow. The slip lengths are complex quantities that are functions of the oscillation frequency, the channel height and the no-shear area fraction of the wall. The dependence of the complex nature of the slip length on the oscillation frequency is investigated in particular.
