can someone tell me what the point of a wind tunnel is.

Why not make a box with string going from one side to another under tension, so when you place an object that you want to analyze, the string is going to get displaced similar to wind...

good luck measuring drag with a string

Not for measuring or specific analysis, but just for general visualization purposes (in intro-level courses, or high school physics)

you can't visualize wakes, vortices, etc. with strings

The string would just deform around the object with no indication of the flow of particles, you goddamned retard.

>>9220823
true. Didn't think of irregular flows.

>>9220857
you dont need indication of flow of particles if it's a steady flow you asshat.

Because that's not how string works, you fucking idiot. It's not going to adhere to the object. Why the hell are engineers so consistently stupid?
