Nonlinear Dynamics in Frontal Polymerization and Combustion

10:00 AM-12:00 PM
Room: Golden Cliff

We consider gaseous and solid fuel combustion as well as exothermic frontal polymerization processes, which are used, in particular, to synthesize materials. Since the structure of the material is determined by the propagation mode of the exothermic wave, various modes must be studied. Analytical, numerical and experimental approaches are employed in a variety of problems, including the dynamics of cellular and hot-spot flames and spinning polymerization modes. Since similar instabilities occur in combustion and polymerization, a joint discussion will be beneficial for researchers in both areas. Thus we want to bring together active researchers with interests in flames, combustion and polymerization waves as well as researchers with interests in nonlinear dynamics in general.
