Non-Newtonian fluid
In rheology, the science of fluids, a non-Newtonian fluid is one whose viscosity changes with the applied shear force.Types of non-Newtonian fluid include:
- rheopectic (viscosity increases with increasing force, as in some lubricants)
- thixotropic (viscosity decreases with increasing force; e.g. non-drip paints; tomato ketchup)
