👉 The neo-fluid, also known as non-Newtonian fluid, is a complex state of matter that defies the traditional Newtonian behavior where viscosity remains constant regardless of applied stress. Instead, its viscosity changes in response to the applied force, often becoming less viscous when stressed and more viscous when relaxed. This unique property is observed in various substances like ketchup, blood, and certain polymer solutions, where the fluid's flow characteristics are highly dependent on the shear rate or applied stress. Understanding neo-fluids is crucial in fields such as biomechanics, materials science, and industrial processes, where their behavior under different conditions significantly impacts performance and design.
