| Abstract: | A model for an elementary detonation cell is postulated. On its basis, the geometry of the cell pattern and the kinematics of the wave fronts forming the cells are evaluated. The cell size is determined assuming that the induction time obeys an Arrhenius relationship with temperature. Thus, it is shown that some kinetic parameters of the mixture, such as the activation energy, can be deduced from the cell size. It is also demonstrated that by combining the cell model with the experimental data on the propagation of the detonation wave in a rapidly expanding channel, the initiation energy for a cylindrical detonation wave can be estimated. |
