“…From the viewpoint of numerical simulation, the task is rather complicated. Here we note its multicomponent nature, the high rigidity of chemical kinetic equations, etc [1,2]. The complexity of the problem is also associated with a sharp temper ature dependence of the chemical rate and a strong change in the density of the gas mixture due to a change in the average molecular weight.…”

The paper presents the mathematical model of combustion initiation in a mixture of hydrogen and oxygen gases (oxyhydrogen) by a laser flare created near a metal barrier. For numerical resolution of the 'hyperbolic' part of Reynold's equations system, we give a new nonlinear quasimonotone compact polynomial difference scheme of improved accuracy. Calculations of all the main parameters: the laser flare, the heating of the metal barrier, and the combustion processes in the hydrogen-oxygen system are performed.
