    Welcome to the PF.

    What is the context of your question? What is the wind tunnel for? What do you know so far about wind tunnel design? Is this for a school project?

    I know a fair amount.I have built the wind tunnel found on Science Buddies Web site.Now I want to scale that up to do smoke testing of my Formula Vee racing car.From the test section size should be able to work out contraction cone size needed.

    What wind velocity do you want to support? Can you show us what work you've done so far? :smile:

    I worked out 15 to 20 m/s.As said have test section area plotted out.How important is contraction cone for only smoke testing.Do not need cd factor and drag etc.
