Where stress is proportional to rate of strain, its higher powers and derivatives (basically everything other than Newtonian fluid). Non-Newtonian fluids are the opposite of Newtonian fluids. When shear is applied to non-Newtonian fluids, the viscosity of the fluid changes.

ANALYSIS The physical configuration is illustrated schematically in Fig. The falling liquid, driven by gravity, flows a down flat heated plate inclined at an angle θ. New models for the prediction of laminar and turbulent flow of non-Newtonian fluids in open channels of different cross-sectional shapes are proposed.

These models are compared with three previously published models for laminar flow and five previously published models for turbulent flow using a recently extended experimental database for non.

Flow of generalized Newtonian fluids in porous media can be modeled as a bundle of capillary tubes or a pore-scale network. In general, both approaches rely on the solution of Hagen–Poiseuille equation using power law to estimate the variations in the fluid viscosity due to the applied shear rate.
