question about horizontal oscillation of naca0012

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.

thank you?

Re: question about horizontal oscillation of naca0

(1). There must be a reason why your airfoil is oscillating. 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.

We are studying a new method to deal with the source term.We select such problem as a test.
