👉 A rational fluid, often referred to as a rational vortex or a vortex generated by a rational flow, is a theoretical concept in fluid dynamics that describes a fluid motion characterized by a continuous, smooth, and predictable pattern of vortices. This type of fluid motion arises from the balance between various forces acting on the fluid, such as pressure gradients and viscosity, leading to a stable and organized structure. Unlike turbulent flows, which are chaotic and disordered, rational fluids exhibit laminar behavior, with vortices forming in a regular, repeating pattern. This concept is particularly useful in understanding and modeling natural phenomena like ocean currents, atmospheric flows, and even the flow of fluids in pipes under specific conditions.
