I'm trying to talk to the right people, but there are so many departments that might use such a thing.
I'm looking for a small-scale wind tunnel at UND or somewhere in Grand Forks that we could use for some geology (geomorphology) experiments for a class. We'd like to blow some sand around an object and be able to measure certain aspects, and apparently it's not "wind-tunnely" to just set up a box fan because you don't get reproducible laminar flow.
If anyone has any ideas, drop me a PM or post here.
