Still there, still playing...

Hi there,

THAT was a long time ago ... I started playing with CFD and must admit it's quite some work, but fun ! After fiddling with 3D, I am now playing with XFOIL, to compare some foil shapes.

I put up a little excel sheet to transform the xfoil variables into somthing standard. I also read on the net that the Ncrit variable should be put to around 3 to have a water behaviour of the turbulence. If you have any other advice, I'm interested of coarse.




Meanwhile, I'm nearly done installing a little room where I hope I'll be playing around with epoxy soon. We saw a very usefull Youtube vid http://www.youtube.com/watch?v=mROBlWIu8q4 of the beaver hull bluiding and it opened my eyes a bit. I'll have to build a team too and we'll probably just copy all the rest... One thing I didn't understand is why they put a layer of aramid under the nomex ; you know ?

Stay tuned, post a comment, happy christmas.
