Milne-Thomson circle theorem
In fluid dynamics the Milne-Thomson circle theorem or the circle theorem is a statement giving a new stream function for a fluid flow when a cylinder is placed into that flow. It was named after the English mathematician L. M. Milne-Thomson.
Let be the complex stream function for a fluid flow with no rigid boundaries and no singularities within . If a circular cylinder is placed into that flow, the complex potential for the new flow is given by
- Potential flow
- Conformal mapping
- Velocity potential
