This book was released on 1974 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The drag coefficient of an object moving in a rarefied gas can be expanded in terms of the inverse Knudsen number. In the reported equation one term represents the drag coefficient in the free molecular flow limit. It is shown that a second coefficient is determined by a set of well defined collision integrals associated with sequences of successive collisions among two molecules and the object. These collision integrals are evaluated for a disc and a sphere assuming that the gas molecules are reflected diffusively by the object. The molecules are treated as hard spheres and the drag coefficient is studied as a function of the velocity of the object. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Drag on a Body in Nearly-Free Molecular Flow A third method, as yet not fully analyzed, has been advanced by Enoch It is applicable to high speed flows for which the distribution functions, which are highly peaked about some average velocity, may be approximated by 6 - functions. The full collision integral is then replaced by a simpler model which, however, retains the three conservation laws. The fore going analysis has been successfully applied to high speed plane Couette flow, the distribution function and its first three moments having been obtained analytically.

Download or read book Aerodynamic Drag and Heat Transfer for Flow Past Two dimensional Bodies at High Knudsen Numbers written by Donald Roger Willis and published by . This book was released on 1966 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
