Abstract:

A final report is made on the transfer of mass, momentum and energy in free-particle and transaction flow systems. It includes a state-of-the-art survey of the kinetic theory of gas flows based on reviews of basic background information. The report describes a study in the free particle regime in the hyperthermal free-molecule flow with application to satellite drag. Schombergs reflection model is applied in the calculation of drag coefficients for convex bodies in free molecule flows and of the torque exerted on the Explorer 6 satellite. The same reflection model is also used for the calculation of the molecular transmission probability for conical tubes in hyperthermal free molecule flow. An experimental electron beam study of diffusive separation in transition-flow aerodynamic situations is noted. A method based on the studies has been developed to determine the ambient temperature and density of the major components of the upper atmosphere. Author
