The present work refers to the study of propellants in droplet form under supercritical conditions. In the first place, the actual importance of the problem is discussed and a brief review is carried out on the theoretical and experimental evidence existing on the problem. A model for the theoretical study of the process is in the first place established assuming spherical symmetry, laminar conditions and a zero thickness flame. Boundary conditions, which are specially significant in this problem, are thoroughly analyzed, showing that complete stationary theories cannot be applied. Further assumptions are introduced in order to solve the problem which lead to the study of two different models of the process, which differ, essentially, on the physical conditions assumed at the droplet surface.
