Modeling of Energy Transfer during Combustion of Low-Gas Thermal Compositions in Systems with Intensive Heat Removal
ABSTRAKT
Models of heat and mass transfer during combustion of pyrotechnical compositions in systems with an inert substrate are analyzed. A design of a scanning cylindrical calorimeter for experimental investigation of energy transfer processes during combustion of pyrotechnical compositions is given. Methods of measuring the transfer potentials in the combustion wave and thermal decomposition products are presented. Thermal balance components, including time-integrated establishment of the equilibrium temperature in the "thermal composition substrate" system and front-differentiated combustion wave, are assessed. The modeling results of the process of combustion of iron-magnesium thermite in a cylindrical metal shell are discussed.
