Question

Vortex in a Pipe / Solutions or approximations?

Answer 1

A couple introductory texts on fluid mechanics (e.g. Shames, Mechanics of Fluids) describe the solution to vortex flow in 2D:

Vθ=Γ(2πr)Vθ=Γ(2πr)

(with a singularity at the center). However, what about a vortex in a pipe?

If I assume irrotational flow down a pipe, can I establish a helical vortex (e.g. VrVr = 0; VzVz > 0; VθVθ> 0)?Is it merely superposition (e.g. irrotational 2D + parabolic laminar or irrotational 2D + plug flow)?

Is there a reference you can suggest to read about this phenomena?

If this is solved using CFD, then how do I identify which types of CFD are appropriate? Is this still merely a potential flow? What is the simplest CFD that would solve this type of problem?

Answer 2

Hola mate !! ✨✨

here's your answer ...⬇️⬇️

A vortex is a circulating mass of wind or fluid that moves so fast that it attracts all objects towards it in its close vicinity .


Vortex in a pipe or solutions can be created if there is irrotational flow of fluid through it .

hope it helps !! ❤️❤️
