👉 Duke fluid, also known as non-Newtonian fluid, is a complex biological fluid found within the blood vessels of the human body. Unlike Newtonian fluids, which have a constant viscosity regardless of applied force, Duke fluid exhibits a unique property: its viscosity changes in response to shear stress. Under normal conditions, it behaves like a viscous fluid, but when subjected to increased shear stress (such as during rapid blood flow), it temporarily thins out, allowing for smoother and faster movement through narrow capillaries. This adaptive behavior is crucial for efficient blood circulation, particularly in areas with high flow rates, and plays a significant role in maintaining optimal blood pressure and oxygen delivery throughout the body.
