A generalized Newtonian fluid is an idealized fluid for which the shear stress is a function of shear rate at the particular time, but not dependent upon the history of deformation. Although this type of fluid is non-Newtonian (i.e. non-linear) in nature, its constitutive equation is a generalised form of the Newtonian fluid. Generalised Newtonian fluids satisfy the following rheological equation: where is the shear stress, and the shear rate. The quantity represents an apparent or effective viscosity as a function of the shear rate.

  • A generalized Newtonian fluid is an idealized fluid for which the shear stress is a function of shear rate at the particular time, but not dependent upon the history of deformation. Although this type of fluid is non-Newtonian (i.e. non-linear) in nature, its constitutive equation is a generalised form of the Newtonian fluid. Generalised Newtonian fluids satisfy the following rheological equation: where is the shear stress, and the shear rate. The quantity represents an apparent or effective viscosity as a function of the shear rate. The most commonly used types of generalized Newtonian fluids are: * Power-law fluid * Cross fluid * Carreau fluid * Bingham fluid It has been shown that Lubrication theory may be applied to all Generalized Newtonian fluids in both two and three dimensions.
