Generalized Newtonian fluid
A generalized Newtonian fluid is an idealized fluid for which the shear stress, τ, is a function of shear rate at the particular time, but not dependent upon the history of deformation.
Additional recommended knowledge
where: ∂u/∂y is the shear rate or the velocity gradient perpendicular to the plane of shear (SI unit s−1).
represents an apparent or effective viscosity as a function of the shear rate (SI unit Pa⋅s).
The most commonly used types of generalized Newtonian fluids are:
