hi i need help for my final year project topic:COMPLETE DESIGN OF WIND TUNNEL

Dear santosh sharma:

Do not use all caps. It conveys that you are shouting.

Google comes up with one hit that might be useful to you.

Otherwise, you probably will need to hit a university library.

David A. Smith

Suggest you get to library and learn how do use a reference librarian's search tool. Not everything on needs to now is on the net.

Low Speed Wind Tunnel Design by Pope. There are also High speed and testing books as well.

References have been given. You are not going to find pdfs of these old copyrighted works. If you have specific questions, pose your problem and ask them here. I and others might help you then, but we are not going to spoon feed you.

ok thanks Ed Ruf i wan the specific calculations of the materials used and moreover i want to use the car's propeller as a fan as i can't buy new one becoz its costy. is it possile and how would i respond to the questions like "why i used the contractor and expander of the size i made?" i need the references to design the contractor and expander. that's for now

I gave a reference to

in the other thread . There is a page for each component on the site which gives basic guidelines for the diffuser and specific reference for the contraction. In fact a paper is provided with references and the original NASA CR can be found on the NASA Tech Report server site I pointed to in another earlier reply. All this stuff is out there on the web. You have to do some of the work yourself.
