“…To render the equations dimensionless, the following scaling relations will be used for the independent and dependent variables The scaling used here for the reduction of the equations to dimensionless form is standard in the combustion literature (Merzhanov et al, 1973;Merzhanov and Borovinskaya, 1975). The scaling variable x* represents an approximate measure of the heating zone length, and x* f t , is an approximate measure of the reaction front propagation velocity.…”

Transition metal nitrides can be synthesized in the combustion regime using a self-propagating, high-temperature synthesis by the process of filtration combustion. A detailed two-dimensional numerical study for the filtration combustion process in the cross-flow configuration is presented. The process is modeled by a two-dimensional pseudohomogenous model. The model equations, which are very stiff and exhibit varying time and length scales, are solved using finite differences on a two-dimensional orthogonal adaptive mesh. The effects of pressure, bed height and bed porosity on combustion front propagation and final conversion are studied. A series of full simulations for the titaniumnitrogen system shows good agreement between theoretical predictions and experimental observations.

“…Other terminologies used to describe the process include self -propagating high -temperature synthesis ( SHS ), and gasless combustion. The current interest in the topic can be credited to the pioneering work of Merzhanov and his group in Russia starting in the early 1970s [1] . However, the process itself has a much longer history.…”

In this paper study the microstructure of the wave self-propagating high-temperature synthesis (SHS) to find the relationship between the rate of the reaction front, the characteristic size of foci and the combustion temperature. Measure the dynamics of the temperature field SHS process was carried out using of the original optical complex of micropyrometer with a spatial resolution of 5.9 mkm and a speed of recording up to 10,000 frames per second. A method of analysis of thermal data implemented on the basis of ergodic model of the wave regime SHS and MATLAB. In the experiment is varied composition Ni-Al and its initial temperature. The experiment results approximated of the quadratic dependence of the rate of the front reaction on the hearth size, and inverse dependence of the hearth size on combustion temperature and initial temperature of the reaction mixture.
