The difference between Newtonian fluids and non-Newtonian fluids
Thread Content
As the title suggests, in the actual production process, which ones are Newtonian fluids and which ones are not? Thank you
A fluid in which the shear stress at any point is linearly proportional to the rate of shear deformation is called a Newtonian fluid. Newtonian fluids are low-viscosity fluids that deform easily under stress, with the shear stress being proportional to the rate of deformation. Any fluid that is not a Newtonian fluid is classified as a non-Newtonian fluid.
Liquids and gases with low viscosity, such as water and light oils, are Newtonian fluids, while liquids with high viscosity, such as polymeric polymers, are non-Newtonian fluids.
