Based on the combustion dynamics model of self-propagating high-temperature synthesis process, numerical simulation and computer simulation are used to analyze and simulate the characteristics of combustion wave and its variation. The results show that with the change of parameters, various spatiotemporal and ordered dissipative structures appear in the combustion wave during the process of SHS synthesis. Nonlinear dynamic mechanism analysis shows that two strongly coupled nonlinear dynamic processes in the system are the dynamic causes of dissipative structures.
