Modeling of boundary conditions in strength analysis of explosion chambers

When solving problems related to the strength of explosion chamber walls, it is crucial to model the pressure fields that arise due to the detonation of gas mixtures inside the chamber. Two cases are considered: one assuming instantaneous detonation of the mixture and another assuming a finite propagation speed of detonation waves. It is shown that taking into account the finite propagation speed of detonation waves is necessary, as in this case, the resulting pressure can exceed the pressure calculated under the assumption of instantaneous detonation by more than 7.5 times.
