👉 An imposed fluid refers to a substance or medium that is artificially introduced into a system or environment, often against its natural tendency to resist change or flow. This can occur in various contexts, such as in fluid dynamics where an external force or boundary condition forces a fluid to move in a specific way, or in biological systems where an organism might introduce a fluid into its environment to facilitate certain processes like nutrient transport or waste removal. The term emphasizes the external influence that compels the fluid to behave in a manner contrary to its intrinsic properties, such as viscosity or pressure gradients.
