👉 A switched fluid, also known as a shear-thinning or pseudoplastic fluid, is a type of non-Newtonian fluid whose viscosity changes in response to applied shear stress or shear rate. Under normal conditions, these fluids exhibit higher viscosity and resist flow. However, when subjected to increased shear, such as stirring or pumping, their internal structure breaks down, allowing the fluid to flow more easily. This behavior is due to the alignment or disruption of particles or polymer chains within the fluid, which reduces resistance to flow. Switched fluids are utilized in various applications, including industrial processes, biomedical devices, and consumer products, where their unique flow properties can enhance performance and efficiency.
