Quasi-Hydrostatic Model of the Combustion of Compositions Forming Molten Reaction Products in the Presence of Centrifugal Forces

详细

A mathematical model of the exothermic chemical transformation of a high-calorie mixture in the presence of centrifugal forces is considered. The process is studied for the 3NiO + (2 + α)Al → Al₂O₃ + (3 − α)Ni + αNiAl thermite composition, as an example. Such processes are used in high-temperature synthesis for the production of target products in the combustion wave propagating through the initial mixture. This technological process represents a combination of high-temperature combustion with the formation of liquid products, their separation, and subsequent cooling. A distinctive feature of the proposed model is the use of a “through” description, which makes it possible to examine the mutual influence of the individual stages on the dynamics of the process. This feature provides a more realistic description of the actual process.
