Numerical study of the problem of thermal ignition in a thick-walled container

A problem of thermal ignition of an exothermic mixture with an inert filler in a thick-walled container is formulated. It was found that synthesis can be performed under conditions of a weakly changing temperature if an inert filler is added to the mixture. Variation of critical conditions separating different thermal regimes with different values of model parameters is examined: ignition and extinction or ignition and slow transformation.
