👉 A describing fluid, also known as a rheological fluid or pseudoplastic fluid, is a material whose viscosity changes in response to applied shear stress or strain. When subjected to low shear rates, these fluids exhibit high viscosity, behaving more like a solid, but under higher shear rates, they flow more easily, similar to a liquid. This unique property is due to the alignment or breakage of internal structures within the fluid, such as polymer chains or particles. Describing fluids are commonly used in various industrial applications, including coatings, paints, and adhesives, where their ability to flow under stress can enhance application processes while maintaining structural integrity when at rest.
