Abstract
The structure and stabilizing mechanism of a subsonic hydrogen / air jet lifted flame are numerically investigated using DNS. The lifted flame consists of an inner premixed flame and outer diffusion flames. The flame base is premixed, which sustains the vigorously turbulent inner premixed flame. The outer diffusion flame consist of several island flames, which are produced from the inner premixed flame. The stabilization at the flame base is maintained by the balance between the axial velocity and the laminar flame velocity. Deviation of heat release layer from hydrogen consumption is observed in the inner premixed flame.
