DEVICE FOR DETERMINING THE COEFFICIENT OF SKIN FRICTION [PDF]

open access: yesProceedings on Engineering Sciences, 2019
Skin tribology is very important scientific area because of its presence in everyday life in form of friction in contact of skin surface and various materials. The most often it appears between palm skin and fingers and object which are in someone hands (

Low friction layer in sanitary products for reduced skin irritation [PDF]

open access: yesScientific Reports
Sanitary napkins are essential during menstruation, but they can sometimes cause skin irritation due to friction. In this study, we propose a novel design: introducing a low-friction layer within the bulk of a sanitary napkin.

Skin friction coefficient on a yarn package surface in ring spinning

open access: yesTextile Research Journal, 2004
The skin friction coefficient on the surface of a rotating yarn package affects the power required to drive the package. This paper examines the relationship between the skin friction coefficient on the package surface and its diameter and rotating speed,

Characterization of skin friction coefficient, and relationship to stratum corneum hydration in a normal Chinese population. [PDF]

open access: yesSkin Pharmacol Physiol, 2011
<i>Background and Objectives:</i> Studies have demonstrated that some cutaneous biophysical properties vary with age, gender and body sites. However, the characteristics of the skin friction coefficient in different genders and age groups have not yet been well established.

Unsteady Magnetohydrodynamic Mixed Convection Flow over a Rotating Sphere with Sinusoidal Mass Transfer [PDF]

open access: yesJournal of Heat and Mass Transfer Research, 2022
This paper investigates the unsteady magnetohydrodynamic (MHD) mixed convective fluid flow over a rotating sphere. An implicit finite difference scheme, together with quasi-linearization, is used to find non-similar solutions for the governing equations.

Bio-inspired Surface Texture Fluid Drag Reduction using Large Eddy Simulation [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2023
Skin friction drag can be reduced through the application of bio-inspired riblet surfaces. Numerical simulations were performed using Large Eddy Simulation (LES) to investigate the effect of using riblets on reducing skin friction drag.

Body mapping of skin friction coefficient and tactile perception during the dynamic skin-textile interaction

open access: yesErgonomics, 2022
The clothing fabric and skin interact continuously across the many regions of users′ bodies during wear, which can lead to both physical skin damage and discomfort. Therefore, this investigation aimed to explore the regional differences in skin friction, tactile perception, and sensitivity in both females and males during the skin-textile interaction ...

Wax-oil lubricants to reduce the shear between skin and PPE

open access: yesScientific Reports, 2021
Prolonged use of tight-fitting PPE, e.g., by COVID-19 healthcare workers leads to skin injuries. An important contributor is the shear exerted on the skin due to static friction at the skin-PPE interface.

Integral relations for the skin-friction coefficient of canonical flows

open access: yesJournal of Fluid Mechanics, 2022
We show that the Fukagata et al.'s (Phys. Fluids, vol. 14, no. 11, 2002, pp. 73–76) identity for free-stream boundary layers simplifies to the von Kármán momentum integral equation relating the skin-friction coefficient and the momentum thickness when the upper bound in the integrals used to obtain the identity is taken to be asymptotically large. If a

Decomposition of the skin-friction coefficient of compressible boundary layers

open access: yesPhysics of Fluids, 2023
We derive an integral formula for the skin-friction coefficient of compressible boundary layers by extending the formula of Elnahhas and Johnson [“On the enhancement of boundary layer skin friction by turbulence: An angular momentum approach,” J. Fluid Mech. 940, A36 (2022)] for incompressible boundary layers.
