Traveling wave solutions for detonations in a viscous combustion model is
studied. The model describe the detailed structure and the propagation of a
reacting gas front into a combustible mixture. It was derived from the one
dimensional combustion equations written in lagrangian coordinates for a simple
Reactant?Product mechanism. Also for mathematical
reasons, the case of exothermic reaction is considered. Traveling wave solutions
for this model are specific heteroclinic orbits of a system of ordinary
differential equations connecting unburned state points to burned state points.
The existence of these solutions are based on some general results in ordinary
differential equations. These results are proved by topological arguments. The
uniqueness of these waves are also considered.
Key words: Combustion, Shock waves, Traveling waves. AMS subject classifications: 34B10, 35K50, 54H20, 80A25. ? |
