The purpose of this research calculates the properties and fuel mixing distribution of high-load burner by the computation fluid dynamics code PHOENICS. The turbulence model is adopted and the control-volume integration for finite difference associated with SIMPLEST algorithm are employed to simulate the three-dimensional high-load burner flowfield. The effects of fuel distribution on high-load burner are jet position, jet diameter, and jet injecting velocity .
The computed results show that the diameter of jet strongly affects fuel mixing distribution profile of main flame orifice. A better outlet fuel mixing distribution profile of the main flame orifice and even the most distribution is shown and which makes a closer approach to the theoretical mass ratio of chemical reaction at condition of the jet diameter d=2 mm, jet position x=0.098 m, injecting velocity 30 m/s, and Reynolds number Re=4.14×10 .
Key words ：high-load burner, main flame orifice , theoretical mass ratio
