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

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
Phase-doppler velocimetry and two-dimensional laser-induced florescence of OH have been used to investigate flame stabilizating in the near field of a spray jet of methanol above an air-blast injector. Comparison between the size-classified velocity fields and the scatter plot of lift-off locations
