- having zero rotation or curl; describing a vector field where no circulation occurs around any closed path
Usage: mathematics; physics
Examples

- An irrotational flow has no vorticity at any point.
- The electric field produced by static charges is always irrotational.
- In fluid dynamics, irrotational motion means the fluid particles do not rotate.
- The mathematician proved that the vector field was irrotational throughout the domain.
- Irrotational flows can be described using a velocity potential function.
