Test cases for inverse aerodynamic design
Autor: Antony Jameson, John C. Vassberg
Publikováno v: Computers & Fluids. 223:104923
What do you get a distinguished Englishman (who has everything) for his birthday? Another publication, but of course! The dilemma is in how to keep it a surprise, while developing a document which warrants his authorship. No problem, Antony and I hav
