The flow field and mixing characters of high efficiency vortices in one type of Radially Stratified Flame Core Burner RSFC where analysed through Cold computing fluid dynamics model CFD in accordance with Mathematical model for flame visualization. The model gives good results and clears the important aerodynamics features of a typical low Nitrogen Oxides NOx of internal staging schematic. The model can be used to evaluate this design performance or to get the necessary information for development its efficiency in accordance with the global demand to clean energy with high efficiency and low NOx emissions. The mixing of this burner dominated by coherent structures, so it is outperform the molecular diffusivity and the length which fluids will mix is independent of the fluid velocity and can determined only from Taylor macroscale which related by the physical size of the fluid domain or in better understanding with the internal recirculating zone dimensions because it is form a region for axial mixing for species and smear out their residence time distribution.

coherent structure, gaseous mixing characters, internal staging schematic flame, cold flow flame model, Taylor macroscale, internal recirculation zone, penetration theory.
