Abstract

Effect of heat loss on heterogeneous flame propagation and its extinction in Self-propagating High-temperature Synthesis (SHS) process have been studied. Results show that the heat loss not only reduces the burning velocity of the heterogeneous flame propagation but also contracts the range of flammability, with causing flame extinction, which occurs in a well-known turning point behavior like a gaseous premixed flame. The present calculations emphasize that not only the mixture ratio, the degree of dilution, and the initial temperature, but also the particle size of non-metal particles strongly influences the flame extinction due to heat loss. It is further demonstrated that the theoretical calculations agree fairly well with existing experimental data in the literature.
