| 摘 要： | IntroductionDiffusion flames have been widely applied inindustrial processing systems,such as large- scaleglass- melting furnaces and hazardous wasteincinerations1] .A numerical model is veryimportant for understanding the complexinteractions between the flow and the chemicalreactions. The laminar hydrogen/air diffusionflame is chosen.Hydrogen/air flame is easier toset up under the laboratory conditions,hence thenumerical model can be verified easily by oneexperiment.Furthermore,hydrogen/air…

| Abstract: | A numerical simulation model is developed for a laminar hydrogen/air diffusion flame. Nineteen species and twenty chemical reactions are considered. The chemical kinetics package (CHEMKIN) subroutines are employed to calculate species thermodynamic properties and chemical reaction rate constants. The flow field is calculated by simultaneously solving a continuity equation, an axial momentum equation and an energy equation in a cylindrical coordinate system. Thermal diffusion and Brownian diffusion are considered in the radial direction while they are neglected in the axial direction. The results suggest that the main flame is buoyancy-controlled. |
