Non-Newtonian fluids are encountered in various engineering applications. This course introduces concepts required to analyze the behaviour of such fluids. Since micro-structural features of materials are responsible for non-Newtonian nature, this course describes the most commonly used classes of material systems and their rheological behaviour.
