A numerical simulation was performed to investigate a multi-jet inverse methane diffusion flame. The numerical simulation was established by the commercial CFD code Fluent for an air jet surrounding by four fuel jets. Using a Pre PDF technique to estimate the interaction between the chemistry and turbulent flow. The simulation results show a better data of the flame temperature field characteristics and the CO, CO2, NO H2O, CH4, O2 concentrations. The influence of the velocity of the fuel and air jet on the NO production is appearing very clear. |
