Power Law Fluid 1
Power Law Fluid 1 : (n.) Drilling Fluids. A fluid described by the two-parameter rheological model of a pseudoplastic fluid, or a fluid whose viscosity decreases as shear rate increases. Water-base polymer muds, especially those made with XC polymer, fit the power-law mathematical equation better than the Bingham plastic or any other two-parameter model. Power-law fluids can be described mathematically as follows: See: Bingham plastic model, centipoise, direct-indicating viscometer, Herschel-Bulkley fluid, Newtonian fluid, non-Newtonian fluid, plastic fluid, pseudoplastic, rheological property, rheology, shear rate, shear stress, viscosity, XC polymer
