Recent experiments in microgravity suggest the possibility of statiomtry spherical premixed flames (flame balls) in which the only fluxes are diffusional. We construct stationary solutions of this nature, stm-ting with simple model equations and using activation energy asymptotics. Sufflcionfly larg

The method of matched asymptotic expansions, in terms of a suitably reduced activation energy, is applied to investigate the effects of heat losses on linear stability of a planar flame, which is governed by a one-step irreversible Arrhenius reaction. The density change associated with the heat rel
A theory of spherical premixed flames in which the only transport processes are diffusion and radiation ("flame balls") is extended to include the effects of heat loss from the far-field (unburned gas). Using matched asymptotic expansions for large activation energy, stationary solutions are constru
