👉 The Morris fluid, also known as the Morris-Casson fluid, is a non-Newtonian fluid that exhibits shear-thinning behavior, meaning its viscosity decreases with increasing shear rate. This unique property arises from its complex molecular structure, which consists of long, entangled polymer chains that align and slide past each other under stress, reducing internal resistance. As a result, the fluid flows more easily when subjected to higher shear forces, such as those encountered in industrial processes or natural phenomena like blood flow. This characteristic makes the Morris fluid highly useful in various scientific and engineering applications, including modeling biological fluids, studying material behavior under stress, and optimizing industrial mixing processes.
