Hill's spherical vortex is a theoretical fluid dynamic model that describes a specific type of vortex flow in a three-dimensional, inviscid (non-viscous) fluid. Named after the mathematician G. W. Hill, this model illustrates a steady, symmetrical vortex structure that can be used to analyze the behavior of fluids in terms of rotation and circulation.
