Skin Friction Resistance of Ships

Skin friction blistering: computer model.

BACKGROUND/PURPOSE Friction blisters, a common injury in sports and military operations, can adversely effect or even halt performance. Given its frequency and hazardous nature, recent research efforts appear limited. Blistering can be treated as a delamination phenomenon; similar issues in materials science have been extensively investigated in theory and experiment. An obstacle in studying bl...

In 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 ...

study of skin friction in channels by lattice boltzmann method

a finite volume-lattice boltzmann algorithm is applied to study skin friction behaviour in different channel flows. for this purpose, cell centred scheme is adapted to discretize the boltzmann equation and consistent boundary conditions are also addressed, which resulted in a wider domain of stability. a simulation of flow in a two dimensional channels with different geometries are carried out....

Friction Ridge Skin: Morphogenesis and Overview

The friction ridge skin occurs on the palmar sides of the hands and the plantar sides of the feet of all primates, including humans. As the name implies, the skin is ridged to produce friction. The friction aids in grasping and walking. The friction ridge skin also contains numerous sweat glands, and the pore openings are located along the tops of the ridges. The friction ridge skin does not co...
