👉 The Clarke fluid, also known as the Clarke-Cook fluid, is a non-Newtonian fluid that exhibits shear-thinning behavior, meaning its viscosity decreases as the shear rate increases. This unique property allows it to flow more easily under stress, such as when a bottle is turned upside down, while still maintaining enough resistance to resist flow under low shear conditions. This characteristic makes it useful in various industrial applications, including food processing, cosmetics, and pharmaceuticals, where controlled flow and stability are essential.
