Understanding Non-Newtonian Fluids

Non-Newtonian fluids are fascinating substances that don't follow traditional fluid dynamics. Unlike Newtonian fluids, such as water or oil, which have constant viscosity, non-Newtonian fluids change their viscosity in response to stress or force applied to them. This means their flow behavior can vary depending on factors like pressure, shear rate, or temperature. Examples of non-Newtonian fluids include cornstarch and water mixtures, known as oobleck, which behave like a solid under sudden force but flow like a liquid when left undisturbed. Other examples include ketchup, toothpaste, and even blood. Understanding these unique properties has applications in various fields, from industrial processes to medical treatments and beyond.
