| Popis: | The numerical modeling method of detonation wave propagation proposed in earlier work for gas volumes of finite thickness was used in this paper with a more adequate description of the chemical kinetics to compute the critical gas layer thickness of the mixtures 2H/sub 2/ + O/sub 2/, 29% H/sub 2/ + 71% air, 23% H/sub 2/ + 77% air, and 4H/sub 2/ + O/sub 2/. To model the detonation wave propagation, two-dimensional gas dynamic equations in the Lagrange description were taken, supplemented by the chemical kinetics equation in Arrhenius form. A formula was derived for computing specific heat liberation. Results are presented of computed detonation wave velocities for different values of the effective specific heat of combustion as well as for values of the Chapman-Jouguet velocity for the mixtures. |
