摘要: Combustion at the microscale shows an immeasurable potential in fields of energy utilization and microelectromechanical systems (MEMS) due to its novel combustion characteristics. Studying mechanism this kind is great significance for deepening understanding microcombustion phenomena designing related devices. In article, non-premixed H2/O2 a two-dimensional Y-shaped microchannel with height 10 μm was numerically studied using direct simulation Monte Carlo (DSMC) method. The total collision (TCE) model kinetic including six species seven reversible reactions were employed. Predicted distributions velocity, temperature, heat flux, components inside are presented analyzed. Influences Knudsen number wall surface conditions on characteristics discussed. results show that exothermic reaction mainly takes place junction area branch c...
