Recently, tubular flames are considered due to theiradvantageous in geometry of the flame. The majorimportance of tubular flame which makes it different fromother flames is its uniform temperature distribution.Therefore, it may reduce the formation of thermalfluctuations and hot spots along the furnaces. In this paper,a non-premixed tubular flame is simulated with Methane asfuel. Numerical results are validated against theexperimental measurements. The structure of the tubularflame in the middle of the combustion chamber isinvestigated. Two types of chemical mechanism includingglobal and DRM22 are evaluated.
