明显粘度的定义
Apr 15, 2025
Apparent viscosity is a key parameter for measuring fluid fluidity, referring to the ratio of shear stress to shear rate at a specific velocity gradient, used to characterize the viscous characteristics of non Newtonian fluids. Its core lies in reflecting the "apparent viscous resistance" exhibited by fluids during flow, which varies with shear rate and contrasts with the constant viscosity of Newtonian液体.
