AbstractCombustion is a complex problem involving multi-stage chemical reactions and multi-scale physics. The microscopic process of chemical reactions has obvious stochastic character and may bring important influence to combustion phenomena both locally and globally. In this study, we employ a stochastic simulation algorithm (SSA) to simulate the microscopic hydrogen-oxygen auto-ignition process. Statistical result of SSA calculation shows that fluctuation is controlled by both temperature and microscopic volume. The non-homogeneous distribution of radicals caused by local fluctuation may cause the difference between average microscopic quantities and their macroscopic counterparts due to some radical-radical reactions.
