摘要
In order to guide combustor design process, the mult-dimensional calculation has been developed. A zonal approach, wherein the flow field is divided into two zones, i.e. the burner liner and the transfer jointing section, is developed. This approach permitted three dimensional and two phase and three dimensional axisymmetric reacting flow compute codes to be used in the two various zones. The turbulence effects are simulated using the standard k-ε turbulence model. To improve the k-ε-g turbulent combustion model, an expression of model coefficients C_R is employed. The modified Flux model is used to predict the radiant heat transter characteristics. The predictions of velocity profiles, fraction and wall temperature,show that the present approach is useful for combustor design and development.
