Wind Tunnel Effect

How would I be able to replicate a wind tunnel? I tried with particles and simple shapes but the particles weren’t going around the shapes.

If you’re looking to fake it, curve guides would work, if you’re looking for actual simulation, then maybe, at best, you might be able to use the fluid engine, but I wouldn’t bet on it. Blender is NOT a technical simulator.

Well I thought I should try out the fluid sim. I just wanted to see if it would work in Blender. I haven’t used Blender in a while so I have to get used to it all over again. I’m going to learn more about how to get the fluid sim working 'cause i have no idea.
