Abstract:
It is shown that the steady-state gasification of a homogeneous energetic material with exothermic subsurface reactions has stability boundaries for small and large values of the radiant flux. Examples of corresponding calculation using a transient combustion model are given. A possible method of accounting for the subsurface reactions on the transparency of an energetic material is considered (with examples of numerical calculation). The gasification rate response function of an inert material to small variations in the radiant flux is found analytically. Knowledge of this function allows one to obtain information on some thermal and optical characteristics of an energetic material using relatively simple experiments.
Keywords:gasification by radiation, transparency, instability, energetic material.
