👉 The h-fluid, also known as the hyper-viscous fluid or pseudoplastic fluid, is a complex material that exhibits a unique property of increasing viscosity under shear stress. Unlike typical fluids where viscosity remains constant, h-fluids flow more easily when subjected to mechanical stress, such as stirring or pumping. This behavior is due to the alignment and rearrangement of their molecular structure, which reduces internal resistance to flow. Examples include certain blood plasma under shear stress, ketchup, and some biological tissues. This property makes h-fluids useful in various industrial applications, from food processing to biomedical engineering.
