Cross model
“describes pseudoplastic flow with asymptotic viscosities at zero (n0) and infinite () shear rates, and no yield stress”
Casson Model
used to describe the flow of visco-elastic fluids.
Carneau Model
type of generalized Newtonian fluid where viscosity depends upon the shear rate, The Carreau viscosity model is useful in describing flow behavior of fluids in the high shear rate region.This fluid model is capable of describing both shear thinning and shear thickening phenomena.
