Unsteady combustion of layered condensed systems. Parallel burning of components
S. A. Rashkovskiy Russian Academy of Sciences, Institute of Problems of Mechanics, Moscow, 119256
Abstract:
A model of unsteady combustion of a “sandwich”:-type layered condensed system consisting of parallel layers of simultaneously burning components capable of self-sustaining combustion is considered. The response function of the mass burning rate of the system to periodic pressure oscillations with allowance for the interaction between the components caused by the difference between their burning rates is found. In the linear approximation, combustion of such systems under a rapid change in pressure is analyzed. It is shown that the pattern and duration of these processes depend on the ratio of the layer thickness of the slowly burning component and the thickness of its heated layer. It is found that bending of the burning surface of components in the course of unsteady combustion of the layered condensed system can substantially affect the pattern of its unsteady combustion as a whole, in particular, enhance or reduce its stability.
