👉 The Elliott-Fluid, also known as the Elliott-Fluid-Liquid (ELF) model, is a theoretical framework used in fluid dynamics to describe the behavior of complex fluids, particularly those that exhibit non-Newtonian properties. Unlike traditional Newtonian fluids, which have a constant viscosity regardless of applied shear stress, the Elliott-Fluid model accounts for fluids whose viscosity changes with the rate of shear or strain rate. This model incorporates three primary components: a solid-like component that behaves like a rigid body under certain conditions, a liquid-like component that flows like a fluid, and a yield stress component that prevents the fluid from flowing until a certain threshold stress is applied. This comprehensive approach allows for a more accurate representation of materials such as polymer solutions, suspensions, and biological fluids, making it invaluable in fields like polymer science, food technology, and biomedical engineering.
