## What is circulation flow?

circulation is the line integral of a vector field around a closed curve. In fluid dynamics, the field is the fluid velocity field. In electrodynamics, it can be the electric or the magnetic field.

## What is a circulation lift?

The circulation theory of lift asserts that the difference in air speed over and under the wing results from a net "circulation" of air.
