Extreme Cases of Solid-Fuel Oxidizer Mixtures, by N. N. Bakhman A study was made to ascertain the asymptotic aspect of the dependence of combustion speed of mechanical mixtures of a solid fuel and an oxidizer on the size of the particles of the reagents. In the system of very largesized particles the flame speed, v, strives toward a certain limit as the size of the reagent par icles increases. The value of v is determined chiefly by conditions near the snout of the hollow which develops during combustion. The flame propagation also depends on the chemical nature of the oxidizer and its relative density, and on high pressure. The curve of dependence of the combustion speed upon the size of particles for systems with a continuous boundary of separation of fuel with the oxidizer has an S shape. Note on the Steady-State Theory of Heat Balance in the Condensed Phase of Powder and Explosives, by B. I. Plyukhin A mathematical analysis is presented of heat processes in the condensed phase of steadily-burning powder or explosives. Approximate solutions are given for the equation of heat balance.
