The property or state of being irrotational.
1960McGraw-Hill Encycl. Sci. & Technol. VII. 402/1 For an incompressible fluid, the continuity equation..is div v = 0; hence, combining this relation with irrotationality gives Laplace's equation, div (grad ϕ) = 0. 1967Progress Aeronaut. Sci. VIII. 6 The velocity field is determined by the equation of continuity and the condition of irrotationality. |
