Sentence examples for reduction of the friction from inspiring English sources
Most investigations have been focused on the reduction of the friction coefficient.
Tribological outcomes evidenced a reduction of the friction coefficient when the resin is reinforced by carbon or glass fibers.
More recently, micro-textured surfaces have been investigated for reduction of the friction and wear of two contact interfaces.
However, it is generally accepted that hydrothermal alteration and clay content in shear planes contribute to a significant reduction of the friction angle during fault reactivation (Krantz [1991]).
At the same time, a reduction of the friction coefficient and an increase of wear rate were found.
However, the reduction of the friction drag is competitively balanced with the increase of shock wave induced drag in transonic regime.
That meant the addition of WSe2 nanorods to the base oil resulted in nearly 50% reduction for the friction coefficient of the base oil.
The lifting efficiency increases with the increase of the pipe diameter due to the reduction of the wall friction influence on the flow.
Multifold improvements in the surface dry and lubricated wear life, reduction of the dry friction coefficient, prevention of corrosion attack from the products of PFPAE lubricant degradation, and improvement of salt-fog corrosion resistance are demonstrated.
In particular, we simulate the field-free case to show how finite time effects strongly modify the traditional Coulomb logarithm, resulting in a significant reduction of the dynamical friction force as calculated by standard theoretical formulas.
The reason might be that a thin layer of fine sand acted as rollers for the rolling of the gravel, leading to the reduction of effective friction resistance during the movement; the interactions between particles became more complicated than they just acted as a single-row roller to lubricate the gravel when excessive amount of fine sand was involved.
