Classic fluid mechanics applications involve flows that use a constant viscosity independent of temperature and shear rate. Those fluids are said to follow Newton's law of viscosity and are therefore called Newtonian fluids (Water, most aqueous solutions, oil, air and other gases). However, for some fluids this assumption does not hold. The flow of Non-Newtonian fluids is also encountered in many branches of engineering (physical chemistry, blood mechanics, hair gel, corn syrup, oobleck) and frequently when simulating flow in pipes. The ICFD solver includes the Power-Law model in order to simulate Non-Newtonian flows.
