Laminar premixed and diffusion flames under conditions of negligible effects of gravity were studied. Particularly, the response of spherical premixed flames under rotation and the spreading of unsteady cylindrical diffusion flames were studied. In addition, buoyancy-free burner-supported spherical diffusion flames were generated for microgravity experiments with droplet combustion. Comparison with computationally simulated values revealed information on the governing flame kinetics. Methane addition resulted in the production of a dual luminous zone structure. The extended limits of flammability and extinction were found to be strongly influenced by the combined effects of flame stretch, mixture nonequidiffusion, and radiative loss.
