Analysis of Stokes flow in microchannels with superhydrophobic surfaces containing a periodic array of micro-grooves (2009, background): “Ou et al. (2004), and Ou and Rothstein (2005) conducted experiments on microchannels containing grooves aligned parallel to the flow, or longitudinal grooves.”
Towards an understanding of induced-charge electrokinetics at large applied voltages in concentrated solutions. (2009, result): “Flow past smooth hydrophilic surfaces has been shown to be consistent with the no-slip hypothesis, but b can reach tens of nanometres for hydrophobic surfaces [267, 268, 269] or even several microns over superhydrophobic textured surfaces with trapped nanobubbles [330, 331, 332, 333, 334].”

On the mechanism of turbulent drag reduction with super-hydrophobic surfaces (2015, methodology): “These competing effects can result in either a small decrease (Tsai et al. 2009) or a small increase (Ou & Rothstein 2005), of no more than 5–10 %, in the magnitude of DR in laminar flow, compared to flat interfaces.”
Direct numerical simulations of turbulent flows over superhydrophobic surfaces (2008, background): “Recent work (see Ou, Perot & Rothstein 2004; Ou & Rothstein 2005; Joseph et al. 2006) has shown that liquid laminar drag reduction is achievable in larger channels, using superhydrophobic surfaces (SHSs).”
A note on the effective slip properties for microchannel flows with ultrahydrophobic surfaces (2006, methodology): “The corrections to the effective slip length produced by the curvature are analyzed theoretically and a comparison with available data and related mathematical models is presented.”
