Problem 48P
In an irrotational region of flow, we write the velocity vector as the gradient of the scalar velocity potential function, . The components of in cylindrical coordinates. (r, θ, z) and (u r, uθ, u z), are
From Chap. 9, we also write the components of the vorticity vector in cylindrical coordinates as Substitute-the velocity components into the vorticity components to show that all three components of the vorticity vector are indeed zero in an irrotational region of flow.
