A nonNewtonian fluid is a fluid with properties that are different in any way from those of Newtonian fluids. Most commonly, the viscosity (the measure of a fluid’s ability to resist gradual deformation by shear or tensile stresses) of nonNewtonian fluids is dependent on shear rate or shear rate history. Some nonNewtonian fluids with shearindependent viscosity, however, still exhibit normal stressdifferences or other nonNewtonian behavior. Many salt solutions and molten polymers are nonNewtonian fluids, as are many commonly found substances such as ketchup, custard, toothpaste, starch suspensions, maizena, paint, blood, and shampoo.
In a Newtonian fluid, the relation between the shear stress and the shear rate is linear, passing through the origin, the constant of proportionality being the coefficient of viscosity. In a nonNewtonian fluid, the relation between the shear stress and the shear rate is different and can even be timedependent (Time Dependent Viscosity). Therefore, a constant coefficient of viscosity cannot be defined.
Although the concept of viscosity is commonly used in fluid mechanics to characterize the shear properties of a fluid, it can be inadequate to describe nonNewtonian fluids. They are best studied through several other rheological properties that relate stress and strain rate tensors under many different flow conditions—such as oscillatory shear or extensional flow—which are measured using different devices or rheometers. The properties are better studied using tensorvalued constitutive equations, which are common in the field of continuum mechanics.
