Non-Newtonian Stress in an Electrolyte
The Journal of Physical Chemistry B, 2011Analogies are drawn between the dynamics of electrolyte solutions and those of dilute suspensions of charged colloidal particles. The viscosity of both electrolytes and suspensions is a function of the ionic concentration c and of the Peclet number Pe characterizing the ratio of applied shear rate that tends to deform the ionic charge clouds, to ...

Turbulence in Non-Newtonian Fluids
The Physics of Fluids, 1964The dissipation of turbulent energy is examined in incompressible isotropic fluids in which deformation depends only on current values of strain rate (Reiner-Rivlin fluids). For isotropic, homogeneous, decaying turbulence, two special cases are examined exactly—the Gaussian process and the inertial subrange.

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.

Publisher Summary This chapter reviews non-Newtonian lubrication. Newton's law of viscous shear states that the shear stress is proportional to the velocity gradient, or loosely, to the sliding speed divided by the film thickness. Under elastohydrodynamic lubrication (EHL) conditions, where the fluid viscosity is enormously higher by a factor of at ...

Fluids give and flow under stress. Newtonians are the simplest of fluids, and they are characterized by the property that the velocity gradient at a point is proportional to the shear stress at that point, thus $$({\rm{Shear\;rate}})\alpha ({\rm{shear\;stress}})\;\;{\rm{or}}\;\;{{du} \over {dy}}\alpha \tau$$ All other fluids are called non ...
