Abstract
The role of competition between reaction chain branching and termination at various burning stages accompanied by reaction mixture self-heating was studied by mathematically modeling combustion of hydrogen mixtures with air and oxygen at a 1 bar initial pressure. An algorithm was suggested that allowed chair branching to be switched off at various time moments during calculations with retaining all the other, including thermal, parameters. It was shown that the switching off of chain avalanches at any process stage resulted in virtually instantaneous burning termination no matter what level of reaction mixture self-heating was reached.
