BTW, if you find that data, I'd be extremely interested to know *how much* convexity is optimal... I presume the minimum which eliminates the turbulence, but how much that is would be useful to know. Not an easy thing to tuft-test... though I am working on a smoke generator / smoke wand, which could be useful.
