Dynamics of a single bubble with a chemically active gas

It is shown that during adiabatic compression of a gas, because of an increase in the relative number of elementary cells (the characteristic scale of the detonation process), a detonation regime can occur in the microvolume of a bubble. In this case, in view of the sharp decrease in the critical energy of initiation, self-initiation of the gas mixture is most likely caused by an adiabatic increase in the temperature. It is shown that the inertial properties of the liquid lead to strong compression of the products of the instantaneous chemical reaction, and this can be regarded as a main mechanism for strengthening of bubble-detonation waves.
