 May 9, 2001, 09:22 question about horizontal oscillation of naca0012 #1 Du Guest   Posts: n/a hi, I am calculating horizontal oscillation of the NACA0012 airfoil.The airfoil oscillates horizontally with a velocity given by u=-A. sin(kt).A is constant. Now I want to get the experiment data about this question, or data whithc other people have calculated about this question. Could you give me some information about this this data? thank you?

I mean the goal you are trying to accomplish. (2). If you are simulating an application, then the best place to find the data is to do journal search first. (3). If you are doing it just for fun of it, then, you are likely to do the testing yourself as well.
