What are the size of the plywood sheets ?
What is the ratio of reduced models you can test in ?
What is the wind speeds you can simulate ?
IIRC : Lets say these are 4x8 feet sheets. You can have reduced models inside 1x1x2. For a 6 feet wide car, this is a 1:6 ratio for the reduced model. Such ration need winds 6 times faster than the 1:1 ratio, so the 23mph is simulating speeds of 4mph.
Don't hesitate to correct me

PS Thanks a lot for all the information you share on this forum. |
Denis,I'm having trouble with the SD card in my camera.As soon as that is resolved I will capture some images and post in a separated thread.
I don't like to rely on memory any longer,but here are some data about the tunnel which are accurate:
* 3- 4-foot by 8-foot sheets of 13mm plywood were used in the project,two to form the sides,and third,plus cut-offs to cap it off.
* I'll get accurate dimensions for nozzle and return inlet.
* no drag force measurements can be produced,only flow visualization.
Al's closing shop,will catch uo asap,Phil.
