203 Shear Thinning (Pseudoplastic)
Shear thinning (pseudoplastic) is the non-Newtonian behavior of fluids whose viscosity decreases under shear strain. Newtonian fluids and non-Newtonian fluids are so named because of physicist Sir Isaac Newton.
A Newtonian fluid’s viscosity remains constant, no matter the amount of shear applied for a constant temperature. These fluids have a linear relationship between viscosity and shear stress. Examples include water, mineral oil, gasoline, and alcohol.
Non-Newtonian fluids are the opposite of Newtonian fluids (in reality, most fluids are non-Newtonian). When shear is applied, the viscosity of non-Newtonian fluids decreases or increases, depending on the fluid. In the case ...
