WebJul 9, 2024 · For an incompressible flow, ∇ · v = 0. If the flow is irrotational, then ∇ × v = 0. We can introduce a velocity potential, v = ∇ ϕ. Thus, ∇ × v vanishes by a vector identity and ∇ · v = 0 implies ∇ 2 ϕ = 0. So, once again we obtain Laplace’s equation. WebWe conclude that this is a physically possible flow field. 5.
