<p>Can experimental results from wind tunnels be compared to water tunnels given that they operate under the same dimensionless parameters?
If so, is there any significance to repeating a water tunnel study in a wind tunnel?</p>
<p>There’s probably another board to post this question on. Does anyone know of another?</p>
<p>Yes. You have to make sure primarily of two things: the wind tunnel is operating below Mach 0.3 so that the flow is incompressible and then you have to match Reynolds number. After that the results should compare.</p>
<p>Also, this board doesn’t have much of a place for this sort of question, but Physics Forums does. I hope I can say that without violating the ToS, but I don’t think you can really consider them competitors so I think I am in the clear.</p>
<p>Ah good point. Thanks, I forgot about PF. </p>
<p>Was “Yes” in response to my 1st or 2nd question? I’m assuming it’s the first.
If it was in response to my 1st, is there any significance to repeating the water tunnel experiments in a wind tunnel and publishing those results?</p>
<p>Yes was in response to “Can experimental results from wind tunnels be compared to water tunnels given that they operate under the same dimensionless parameters?”</p>
<p>I’ll move the rest of my response over to that forum as it is more appropriate.</p>
