CFD analysis of combustion of pure methane in a venturi type burner (SolidWorks and Ansys Fluent)

The model of this burner is relatively simplified to the original one. There is definitely a need to change dimensions of the venturi in order to provide better mix of methane and primary air as well as change excess air ratio to 15% instead of 0%. Making changes in the design of the burners tip may prove to be a good idea too.
