Semispan Wing Model Testing - Issues & Tunnel Corrections

[RandomGuy88]

Hi, I am wondering if anyone out there has some experience testing semispan wing models in a tunnel. Most of my tunnel experience is 2D testing such as airfoils but I am going to be starting some 3D wing tests soon and I would like to know what sort of issues to expect. For example I have been reading up on the interaction of the tunnel wall boundary layer and the wing root. Are there other potential issues I should worry about that are typical of semispan models? What about tunnel corrections? If anyone has any suggestions on references that would be great.

Thanks!

Read Barlows book on Wind Tunnel Testing. It goes over it in detail.
