Newton,

Sir Isaac, English physicist, 1642-1727.

newton - derived unit of force in the SI system.

Newton disk - a disk on which there are seven colored sectors, which, when rapidly rotated, appear white.

Newton law - the attractive force between any two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Synonym(s): law of gravitation

Newton rings - colored rings on thin surfaces.

newtonian aberration - the difference in focus or magnification of an image arising because of a difference in the refraction of different wavelengths composing white light. Synonym(s): chromatic aberration

newtonian constant of gravitation - a universal constant relating the gravitational force, attracting two masses toward each other when they are separated by a distance.

newtonian flow - the type of flow characteristic of a newtonian fluid.

newtonian fluid - a fluid in which flow and rate of shear are always proportional to the applied stress.

newtonian viscosity - the viscosity characteristics of a newtonian fluid.

As many existing studies show, the turbulent eddy motions and ordered structures in drag-reducing viscoelastic flows are known to exhibit time and spatial scales that are different from those of Newtonian flows [3, 4].

It is worth noting that the relative error in the case of the polymer solution displacement is of the same order as that for the Newtonian flow. Values of the average tip velocity from the numerical and experimental results are shown in Table 3.

Experimental and numerical analysis of the viscous fingering instability of shear-thinning fluids

[28, 29] demonstrated that neutrally buoyant rigid spherical particles moved laterally, a phenomenon that would not be observed in Newtonian flows. For shear thinning fluids, particles tended to move in the direction of the shear stress gradient, from the center toward the outer wall.

The viscoelastic flows tend to be more three-dimensional and more complex than the Newtonian flows. That also explain why the large flow deflection occurs at the low Reynolds number of the viscoelastic.

For the immiscible PCL/PLA blend, the [G*.sub.components] should nearly be changeless in the Newtonian flow (<0.3 [s.sup.-1]) because the entangled structure of the bulk polymers is stable.

The subscript n denotes the Newtonian flow while the subscript p denotes the second-order fluid flow.

The effects of polymer additives on the operating windows of slot coating

Making use of a suggestion made by Lumley (1973, 1978) to account for drag reduction caused by long-chain molecules, the authors of the present paper proposed some years ago that the viscous sublayer for non-Newtonian turbulent flows is generally thicker than for equivalent Newtonian flows and put forward a quantitative model to calculate this effect (Wilson and Thomas; 1985; Thomas and Wilson, 1987).

Additionally, similar inertial effects on the Reynolds numbers scale between [10.sup.-6] and [10.sup.-3] were also noted while this magnitude is well below the regime where inertia is known to play an important role in Newtonian flows.
