Abstract : Using the integral iteration method, theoretical results are obtained for aerodynamic drag and heat transfer in the nearly free molecular regime. The geometries considered are: circular cylinders, inclined flat plates, and wedges, all two dimensional. Perturbation to the free molecular results are obtained correct to order (1/Kn) ln Kn only (Kn is the Knudsen number). The free stream speed ratio is greater than two and the body temperatures range from free stream to recovery. The results are similar to those obtained previously for a normal flat strip, except that for small angle wedges and flat strips at small angles of attack, the drag coefficient is predicted to exceed the free molecular value.
