Ultrafiltration of non-newtonian fluids
Journal of Membrane Science, 1996The current study reports on a series of ultrafiltration experiments using newtonian and non-newtonian fluids (pectine, xanthan and polyacrylamide solutions). For non-newtonian pseudoplastic fluids, the shape of the plot of flux versus log(bulk concentration) is different to the linear decline in flux which would occur throughout. Moreover, we observed

A fluid can be defined as a material that deforms continually under the application of an external force. In other words, a fluid can flow and has no rigid three-dimensional structure. An ideal fluid may be defined as one in which there is no friction.

Classical Non-Newtonian Fluids
2016The aim of this section is to discuss the mathematical properties of the governing equations of some non-Newtonian fluids introduced in Chapter 2, Section 2.4, namely, the Reiner-Rivlin fluid and in particular, the Bingham fluid.

Calendering of non‐newtonian fluids
Journal of Applied Polymer Science, 1986AbstractThe calendering of non‐Newtonian fluids by two rotating cylinders to produce thin films of fluids finds wide application in polymer sheet‐making and food‐drying industries. Theoretical work has previouly been devoted to the symmetrical case where the cylinders are of equal diameters rotating at the same speed.

The Hydrodynamics of Non-Newtonian Fluids. II
Mathematical Proceedings of the Cambridge Philosophical Society, 1949In this paper, the general hydrodynamic theory of visco-inelastic, incompressible, non-Newtonian fluids, developed in a previous paper (l), is applied to the problem of the flow of such a fluid through a tube of circular cross-section. It is found that the absolute values of the normal stress components are no longer uniform over a cross-section of the

Electrokinetics of non-Newtonian fluids: A review
Advances in Colloid and Interface Science, 2013This work presents a comprehensive review of electrokinetics pertaining to non-Newtonian fluids. The topic covers a broad range of non-Newtonian effects in electrokinetics, including electroosmosis of non-Newtonian fluids, electrophoresis of particles in non-Newtonian fluids, streaming potential effect of non-Newtonian fluids and other related non ...

Non-Newtonian and Viscoelastic Fluids [PDF]
, 2012 The theory of non-Newtonian and viscoelastic fluids flourished in the second half of last century with the developments of (molten and dilute) polymers and the growth of materials science and engineering that generated many new products and applications.

Attractors of non-Newtonian fluids
Journal of Dynamics and Differential Equations, 1995The existence of global attractors is demonstrated for the dynamical systems generated by motions of nonlinear bipolar and non-Newtonian viscous fluids and upper bounds are obtained for the Hausdorff and fractal dimensions of the attractors for the bipolar case.

Vortices in Non-Newtonian Fluids.
1985Abstract : The research carried out under the subject contract has been directed to the analysis of the manner in which the vorticity in an incompressible viscoelastic fluid propagates and decays. The fluids considered are such that for shearing flows the shear stress at an instant of time t depends linearly on the history of the velocity gradient in ...

Magnetoplastic effect in non-Newtonian fluids.
AIAA Journal, 1966For thin shells, y can be approximated by unity, and Eq. (2a) adopts the identity of Eq. (1). Figure 1 shows the shell response history computed from Eq. (2) for three different loading rates for the unstable mode (m = 1, n = 30, Ref. 1). Comparison of these curves shows that, with fixed shell geometry, material, and load magnitude, the higher rate ...
