In this chapter we concentrate on a large class of problems arising from the dynamics of incompressible non-Newtonian fluids with nonstandard rheology. By non-Newtonian fluids we mean here fluids which do not satisfy Newton’s law of viscosity, i.e. viscosity is constant and independent of stress.

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 ...

Coaxial Mixer Hydrodynamics with Newtonian and non‐Newtonian Fluids
Chemical Engineering & Technology, 2004AbstractThe performance of several combinations of a wall scraping impeller and dispersing impellers in a coaxial mixer operated in counter‐ and co‐rotating mode were assessed with Newtonian and non‐Newtonian fluids. Using the power consumption and the mixing time as the efficiency criteria, impellers in co‐rotating mode were found to be a better ...

We investigate the entropy generation characteristics of a non-Newtonian fluid in a narrow fluidic channel under electrokinetic forcing, taking the effect of conjugate heat transfer into the analysis.

How could you characterize a liquid? You could start with its color, maybe talk about its smell or taste (watch out!) and consider its acidity (lime juice or soap). But sooner or later you will think about the liquid’s viscosity. The viscosity quantifies what we use to call a “thick” or “thin” liquid.

An Overview of Non-Newtonian Fluid
, 2016A non-Newtonian fluid is a fluid with a viscosity that varied under the action of applied stress or forces. It has novel properties that make them potentially useful in many applications in industrial process.

A Localized Mass-Conserving Lattice Boltzmann Approach for Non-Newtonian Fluid Flows
, 2015A mass-conserved lattice Boltzmann model based on the Bhatnagar-Gross- Krook (BGK) model is proposed for non-Newtonian fluid flows. The equilibrium dis- tribution function includes the local shear rate related with the viscosity and a variable parameter ...

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.
