Reply to: Telltales - Do-over!

Message body

[quote=benedict]Bob, that was very VERY interesting. Thanks for posting that.

Last year some of my co-workers and I spent some time using the water tunnel at the University of Washington doing airflow analysis on a scale model of our building. We couldn't get anywhere near the Reynolds number we needed in the water tunnel (though it proved to be the tool of choice for flow visualization). So one afternoon we took our model and stuck it in the University's smaller wind tunnel (not the Kirsten Wind Tunnel, which is their main one.) Prepping for that afternoon involved (you guessed it) taping gobs of little telltales all over the model.

When I clicked on the link you posted, I thought, "Hey, that looks like our model!" Nope. It's a sectional view of a sail. But the tufts sure looked like the ones from our model!

I've got enough telltales coming to give Gentry's system a try. Have you tried it on your boat? I'm curious how effective you find it.

And erice, thanks for pointing that out. Yeah, I probably do want to move those back.
