Abstract
The paper is a continuation of earlier studies by the author and coworkers on combustion in heterogeneous gas-solid systems. Since spinning combustion is usually treated as 2D thermal instability of planar combustion front, the previous studies took into account basically temperature dependence of reaction rate. In the present study, the reaction rate was also assumed to depend on the conversion degree of solid reagent (parabolic law of retardation). The domain of existence for spinning combustion mode was plotted on the parametric plane “initial temperature-spin head conversion degree”. Over a wide parametric range, the conversion degree in the spin head was found to vary between 0.08 and 0.54. Suggested is a new interpretation of multi-head spinning combustion in the systems under consideration.
