A THERMAL THEORY FOR RATES OF PROPAGATIVE BURNING

摘要

Equations were derived for the steady-state burning of pressed columns of homogeneous mixtures of finely divided fuels and oxidants in which the ingredients undergo crystalline transition, fusion, and vaporization. The kinetics and thermodynamics of chemical and physical changes were considered, as well ad thermal properties and particle size.nThe change in rates of burning as a function of particle size may be calculated from the derived equations. The method used to calculate the percentage of metal powder fuel giving the maximum burning rate is discussed, as well as other factors required for the theoretical evaluation of the data.
