WebPseudoplasticity, or shear thinning, is a non-Newtonian behavior that is desirable for drilling fluids. Power-law and Herschel-Bulkley models describe pseudoplastic behavior, in which the slope—the viscosity—of the shear stress versus shear rate curve decreases as the shear rate decreases. WebMay 17, 2024 · What is Pseudoplastic? Pseduoplastic fluids are liquids or gases whose viscosity increase upon application of a force. The opposite type of fluid for pseudoplastic is Bingham fluid.
