👉 A density fluid, also known as a non-Newtonian fluid, is a substance whose density changes in response to applied stress or shear rate. Unlike Newtonian fluids, which have a constant viscosity regardless of applied force, density fluids exhibit varying viscosity depending on the intensity of the applied stress. This property allows them to behave differently under different conditions, such as flowing more easily when stressed and becoming thicker or less fluid when the stress decreases. Examples of density fluids include certain types of blood, cornstarch suspensions (often called oobleck), and some polymer solutions. These fluids are used in various scientific and industrial applications due to their unique and adaptable characteristics.
