Wind Tunnel Design and RP models

Dear rp-ml:

Just read an article (obtained from Stratasys at ) about
Chrysler Corporation and their use of Genisys 3D printed parts for
aerodynamic design testing. At the end of the article they were describing
Chrysler's Aero/Thermal Development lab's wind tunnel and stated that
"rather than using the conventional solid-wall design, Chrysler built a wind
tunnel with a slotted wall. This type of tunnel is less expensive to
construct and operate, but it still provides high-quality data."

An "affordable" wind tunnel for the masses? Can somebody enlighten me as to
what a "slotted wall" wind tunnel design is? And what the cost to construct
one of these is vs. a conventional solid wall?
Maybe some of our Chrysler friends will be reading this....

Best Regards,

Glenn Whiteside
