Vortex Core

A vortex core is the central region inside a vortex, which is a rotating flow pattern like a tornado or whirlpool. In a vortex, fluid spins around an invisible axis; at the very center—the vortex core—the rotational speed is highest, but pressure is lowest. This core often acts as a zone of intense activity or low pressure, shaping the vortex’s behavior. Understanding the vortex core is essential in fluid dynamics, as it influences how vortices form, sustain, and interact in natural and engineered systems, impacting weather patterns, aerodynamics, and fluid machinery.
