WebThe velocity potential is caused by the irrotationality of the flow field. In addition, it can be defined by a three-dimensional flow. On other hand, when we look at the stream function, it is caused by the conservation of mass. Which in turn is restricted to a two-dimension flow.

Velocity Potential - University of Cambridge

WebA potential flow is a velocity field that satisfies any of the following three equivalent conditions. The results are analogous to those for a conservative force field, though the terminology used may be different. For example, we would not talk about the circulation of a force field and would instead say that the field does no work. WebIf a velocity ﬁeld u is irrotational, that is if ∇ × u = 0, then there exists a velocity potential φ(x,t) deﬁned by u = ∇φ. (4.2) This is a result from vector calculus; the converse is trivially true since ∀φ, ∇×∇φ≡ 0. If in addition the ﬂow is incompressible, the velocity potential φsatisﬁes Laplace’s equation ∇ ...
