Abstract
Stationary spherical diffusion flames can be established with the help of a spherical burner in which fuel is supplied internally to a stationary porous sphere in microgravity. The most important parameter in this configuration is the mass flow rate through the sphere, which can be controlled independently and conveniently. Other relevant parameters are the Damkoehler number, which is proportional to the ambient presure and to the surface area of the sphere, and a measure of the heat loss to the burner. In this study we examine the characteristics of the burner-generated diffusion flame as a function of these parameters, with particular attention given to extinction conditions.
