Theoretical prediction of turbulent skin friction on geometrically complex surfaces
This article can be considered as an extension of the paper of Fukagata et al. Phys. Fluids 14, L73 2002 which derived an analytical expression for the constituent contributions to skin friction in a turbulent channel, pipe, and plane boundary layer flows. In this paper, we extend the theoretical analysis of Fukagata et al. formerly limited to canonical cases with two-dimensional mean flow to a...
متن کاملLife on Human Surfaces: Skin Metagenomics
The human skin microbiome could provide another example, after the gut, of the strong positive or negative impact that human colonizing bacteria can have on health. Deciphering functional diversity and dynamics within human skin microbial communities is critical for understanding their involvement and for developing the appropriate substances for improving or correcting their action. We present...
متن کاملDry friction of microstructured polymer surfaces inspired by snake skin
The microstructure investigated in this study was inspired by the anisotropic microornamentation of scales from the ventral body side of the California King Snake (Lampropeltis getula californiae). Frictional properties of snake-inspired microstructured polymer surface (SIMPS) made of epoxy resin were characterised in contact with a smooth glass ball by a microtribometer in two perpendicular di...
متن کاملIn vivo friction properties of human skin.
In vivo frictional properties of human skin and five materials, namely aluminium, nylon, silicone, cotton sock, Pelite, were investigated. Normal and untreated skin over six anatomic regions of ten normal subjects were measured under a controlled environment. The average coefficient of friction for all measurements is 0.46+/-0.15 (p<0.05). Among all measured sites, the palm of the hand has the ...
متن کاملWetting and friction on superoleophobic surfaces
This article describes the physics of superoleophobic surfaces, combining a recently developed free-energy approach and finite element modeling. We start by investigating the peculiar wetting behavior of such surfaces, originating in their “re-entrant” geometry, and discussing a specific mechanism for the “filling transition”, leading to the loss of superoleophobicity. We then focus on their fr...
