Abstract
AbstractA method of ignition conditions determination for any type of exothermic reaction is proposed. The method is based on the maximum temperatures equation for any kind of kinetic function, which was obtained using the integral equation for phase trajectories. In this case, the asymptotic ignition criterion is defined by the infinitely high sensitivity of maximum temperature to the change of parameters at the limit of ignition. Hence, the critical ignition conditions are determined by the presence of extreme points on the plane: parameter – maximal temperature. On the strength of these ideas, the universal algebraic set of equations for critical conditions calculation for arbitrary kinetic law of reaction product formation was obtained. The application of this method to calculation of the second order reactions allows to define the thermal explosion degeneration conditions and the regions of critical conditions existence. The maximum discrepancy between the results obtained with the results of numerical calculation does not exceed ten percent.
