Abstract: The convective regime of filtration combustion of energetic materials in a cocurrent flow of their combustion products is studied using a model with extremely simplified kinetics and heat transfer, which shows instability of the process. It is shown that the more accurate “two-temperature” model describes a steady-state regime. In this regime, the gas temperature on the “hot” boundary of the heating zone is well below the combustion temperature, and the solid-phase temperature is well below the temperature proposed in recent studies on this topic. It is pointed out that the “two-temperature” approach is unjustified and intragranular nonisothermicity must be taken into account for convective regimes. It is shown that the “three-temperature” model, which takes into account this effect, does not give a stable steady-state solution.
