Friction coefficients of tablet masses
International Journal of Pharmaceutics, 1981Abstract In order to obtain a better understanding of friction during tabletting, the possibility of determination of friction coefficients was investigated using a reciprocating tablet machine instrumented with piezoelectric load washers on the punches and strain gauges at the die wall.

Friction coefficient of skin in real‐time
Skin Research and Technology, 2003Background/purpose: Friction studies are useful in quantitatively investigating the skin surface. Previous studies utilized different apparatuses and materials for these investigations but there was no real‐time test parameter control or monitoring. Our studies incorporated the commercially available UMT Series Micro‐Tribometer, a tribology instrument

Frictional coefficients of multisubunit structures. I. Theory
Biopolymers, 1967AbstractThe theory of Kirkwood for the translational frictional coefficients of structures composed of subunits has been generalized in two ways in order to consider aggregates of nonidentical subunits. One of these generalizations fails when the sizes of subunits are too disparate; the other, derived from a surface shell distribution of frictional ...

Hydrodynamic friction coefficients of coated spherical particles
The Journal of Chemical Physics, 2009The complete set of hydrodynamic friction coefficients for a spherical particle coated with a porous layer and immersed in a viscous fluid is evaluated in analytic form. The coefficients allow the calculation of the flow disturbance caused by the coated particle for any incident flow which satisfies the creeping flow equations.
