Non-Newtonian fluid

A non-Newtonian fluid is a fluid whose viscosity behavior changes when a shear force is applied to it.

Unlike Newtonian fluids, where the viscosity remains constant, the viscosity of non-Newtonian fluids can change depending on factors such as shear rate, shear force, and time. This causes them to have different flow behaviors, which can be viscoelastic or thixotropic.

A well-known example of a non-Newtonian liquid is cornmeal and water, which is liquid when moving slowly but becomes a solid when moving quickly.

Non-Newtonian fluids have practical applications in various fields such as the food industry, paints and coatings, lubricants and oil production.
