here's something or you to do when your not on cfd online. http://aerodyn.org i haven't really checked it out but it seens good. now you can check there before asking questions here

Thanks for your information. I have looked into this site. It is good. But I wish more links to references in every topic, e.g., about the interaction between shock and boundary layer, I find no references.

(1). If one is interested in aerospace engineering in general, it is a nice place to visit. (2). It has a broad coverage, but most are short. Then I guess one can always read the reference materials.

yes now that i've read through the page properly it seems rather thin especially in the inverse design and optimization sections, in fact the whole thing seems rather thin.
