- Abstract
- The onset of surface combustion in still atmosphere is studied by the use of a Rayleigh-type fluid model, in which the surface temperature experiences a sudden increase. The only fluid motion is provided by the emergence of the surface mass flux as a result of a simple one-step irreversible reaction. The result provides some insight into the interaction of the surface energy and mass balance and the roles they play in a surface combustion process. From a stability consideration, a criterion of flammability is established for the nonconvective and low-g environment prevalent in the interior of a space capsule.
