👉 Contributed fluid, also known as colloidal fluid or non-Newtonian fluid, is a complex mixture where fine particles are dispersed within a continuous medium, often a liquid. Unlike traditional Newtonian fluids, which have a constant viscosity regardless of applied stress, contributed fluid exhibits unique properties. Its viscosity can change dramatically with variations in shear rate or applied force, leading to behaviors such as shear-thinning (viscosity decreases with increased shear) or shear-thickening (viscosity increases). This fluidity arises from the interactions between particles and the surrounding medium, making it essential in various applications like paints, cosmetics, and biological fluids, where its non-linear response to stress is crucial for performance.
