Features of SHS process in the reactor of a simple geometric form Free

When developing new hybrid technologies, for example, foundry-SHS (self-propagating high-temperature synthesis) technologies for bimetallic and multi-layer casting, composite materials and others that use heat of SHS reactions, it is necessary to ensure the flow of an exothermic reaction with predicted heat generation. The paper studies the process of SHS with a stationary mode of flow of a solid-phase combustion reaction in reactors of a simple geometric form. It is proved that the amount of thermal energy in the stationary process of SHS is proportional to the energy released by one gram of charge, the rate of chemical reaction and the speed of propagation of the combustion wave. Analytical dependences have been obtained that give the possibility of controlling and adjusting the reactor thermal power (energy release rate) within the limits of using one charge material, which is important when creating a technology for bimetallic and multilayer casting, as well as other technological processes. Based on the idea of a uniform velocity of propagation of the main zones of the combustion wave, the technological velocity of the combustion wave was determined in the work.
