The Integument of Water-walking Arthropods: Form and Function (2007, background): “For a surface with microchannels in the Wenzel state , Min and Kim ( 2004 ) demonstrate that the surface topography generally decreases hydrodynamic drag in the direction of the channels .”
Direct numerical simulations of turbulent flows over superhydrophobic surfaces (2008, background): “Recently, Min & Kim (2004, 2005) performed a direct numerical simulation (DNS) in a channel at a friction Reynolds number Reτ ≈ 180, in which the turbulence was fully resolved, but the SHS itself was modelled as an arbitrary slip length.”
Characterization of superhydrophobic surfaces for drag reduction in turbulent flow (2018, background): “…frictional dissipation, a non-zero streamwise slip velocity indicates a local reduction in drag at the solid–liquid interface, while a non-zero spanwise slip velocity, ws, generally results in a local net drag increase as shown by Min & Kim (2004), Woolford et al. (2009), Jelly, Jung & Zaki (2014).”
On the mechanism of turbulent drag reduction with super-hydrophobic surfaces (2015, neutral): “The earliest DNS studies of turbulent flow in channels with SH walls were performed by assuming uniform slip on both channel walls (Min & Kim 2004).”
Microfluidics: The no-slip boundary condition (2005, methodology): “A similar mechanism was quantified experimentally using trapped bubbles in rough silicon wafers [120] (see also the calculations in [180]) and show promise of decreasing turbulent skin-friction drag [112].”
A theoretical prediction of friction drag reduction in turbulent flow by superhydrophobic surfaces (2006, methodology): “The DNS is used to develop and validate the present theory and serves also as a complement as well as independent verification of the previous study[8].”
Slip on Superhydrophobic Surfaces (2010, background): “This effect is demonstrated in the direct numerical simulation studies of Min & Kim (2004) who performed turbulent channel ﬂow simulations at a friction Reynolds number of Re τ = ( τ w /ρ ) 1 / 2 H /ν = 180 with an arbitrary, but not unreasonable, slip length boundary imposed both parallel and…”
