I have a copy of Pan Air (A502) which is a high-order panel method used for modeling 3D airflow around arbitrary bodies. I've read the manual, but I'm not clear about the units used. As I understand it, the free stream velocity is normalized which implies that all the other geometry is scaled by the same factor used to normalize the free stream velocity to a unit vector. No problem with that. But this is going to affect all the various factors it solves for, namely Cl, Cd, Cm, Cdi, and so on. There's also no place to enter the air density. So my question is how do I rescale the various coefficients to restore the units and take density into account?(adsbygoogle = window.adsbygoogle || []).push({});
