• vortex depth — The vortex depth is the depth below an impeller at which its influence can still be seen in a mixed fluid.
• vortex ring — a stable perturbation in a fluid that takes the form of a torus in which the flow rotates in the section of the torus so that the pressure difference between the inside and outside of the torus balances body forces. The best-known vortex ring is a smoke ring
• vortex shedding — the process by which vortices formed continuously by the aerodynamic conditions associated with a solid body in a gas or air stream are carried downstream by the flow in the form of a vortex street
