Critical Analysis of some Common Assumptions in Combustion Models.

摘要

A brief, qualitative review of some of the basic assumptions used in macroscopic models of solid-propellant combustion is presented. The intent of the review is to discuss the limits of applicability of the assumptions and, thereby, to isolate problems in combustion theory requiring more microscopic analysis. Special consideration is given to such problems as heat conduction in the burning propellant, phase transitions at the surface, characterization of the nonequilibrium environment in the material, and the effects of that environment upon chemical-raction rates. Some relatively new theoretical techniques for analyzing the problems will be discussed, as well as some diagnostic techniques for experimental study and verification. Where possible, specific future investigations are recommended and possible benefits to combustion theory in general are explored. (Author)
